CEREBRL  Wrap the tag in quotes, "This is one tag".   
(Version 2.5.4)

SCROLLESS  I have been comparing Leap and Yep for a few days and I see that they are EXACTLY the same app EXCEPT for...

Yep:

-convenient scanning interface with tagging

-clip documents and web pages

-you add files to the library (link/move is up to you)

-you only view, search and manage you library files

Leap:

-a system-wide file browser (folder tree). Yep also has that but you can only see your library files

-Go Deep mode which lets you view contents of a folder as well as its sub-folders altogether

-Spotlight search right inside the app

-Reveal the file in Finder or the folder tree in Leap (called Location List)

-You can flag files

-Leap also has a 'library' of its own. You mark files as managed and then you select view managed files.

Both Leap and Yep can accept ANY file type, so don't only think that Yep is only a PDF manager. And them being so simlar in the other ways means that should you want both you can easily jump between Leap and Yep without thinking. Learn to use one and you master both.

Well, what i can say is it depends on how your style of working is. If you are going to start tagging only new/important files, you are going to be dealing with a mix of tagged and untagged files. In this case Leap is a better choice.

If you are like me who is going to tag every file and all my files are in one place (one tidy mess), you can just add them all into yep and start tagging. Use the GO Deep in your trial version of Leap to see them all at once. If later on I have new files i will drag them from desktop into yep when my desktop in starting to clutter up.

It takes a bit more work because you have to tag ALL your files. But it benefits you in the end. And Yep is cheaper :) And you get web-clipping and scanning helps you go paperless.

I have tested editing a tagged jpeg in photoshop, moving a folder of tagged files using Finder, and the openmeta tags stay, so no problem here. But if you want, the Description field below the tag box actually writes spotlight comments. Paranoid peeps may copy and paste the tags over while they are tagging a file.

As for Leap vs. Pathfinder as replacement for Finder: Leap is a file-organization tool (tags and search). Pathfinder is a file-operation tool, which is e.g. f you want to let's say copy files easily you can use Pathfinder's dual pane view. They complement each other, and Finder can do both, but doesn't do well in any of them.

What i hope to see improvement in Leap/Yep for now is that the user interface is too busy. It is too 'wordy' (bookmarks and status bar can get some simplifying), there are so many words in the file names, tags and folder names already.

Wow, long post, i'm a wordy guy afterall :) but it clears up my mind, and hope it helps you!

PIK80  The idea of this program seemed nice but I have run into a couple of pretty big problems. One is that I discovered that if you change a folder name in the finder it will completely mess with all the information you made in Leap. While the tags are still applied to the files (I can see the tags under the file names) they no longer show up in the info panel on the right which means that I can't make further edits to the tags if I need to. The same can be said for the description area. The location text at the bottom turns red and there is appears to be nothing that I can do to change this! It is really a bummer because I was looking forward to a good tagging solution and this appeared to be it but there still seems to be some big problems with it.

The other issue is that it doesn’t, to my knowledge, appear to be able to filter out files by too many file types like spotlight does. For an example I don’t think you can say just show InDesign files or just show Illustrator files. If they would just fix those two things this would actually be a pretty good program. Unfortunately I don’t know of another PowerPC equivalent that is like this program.

TOM ANDERSEN  Developer here.

You can use Leap to tag files, but the real power lies in searching your files faster and easier than with Apple's tools.

CTKMND  $59 for a file tagging interface?

Did the US dollar take another drop or what?

NOVASTORM SOFTWARE  This is really an incredible app. I use it constantly throughout the day. I'd like to say though that I wish it could be better integrated into the open dialogs and such, so it would appear alongside save/open dialogs much in the way Default Folder X does. (a good complementary app by the way, since it allows you to apply OpenMeta tags while saving). Regardless though, once you get over the habit of putting things in folders and just start tagging everything, it really begins to feel natural. Five stars.

BUU-SAN  I bought LEAP in order to see if such a software is able to fit with the mess in my brain. Also, I have never read any document about "how to use" correctly this software.

For my brain, a good software should be able to be used intuitively. In that way, LEAP is not so bad.

But I found a complementary software to add tags more easily (Tags.app), by selecting 1 or several docs (email, pdf, image, ...) and pressing CTRL+Space for exemple, a Tag window appear and you can add your tags. They are recognized by LEAP also. That is really very convenient.

I use also Papers to organised my PDF files (list of publications). Papers is nice for bibliography (for scientists) as it generates a folder in which the PDF are classified by year, journals, authors, ... That is great and cheap.

But today, I made a big mistake combining Papers and LEAP, and I want to share this bad experience. I wanted to add tags on some PDF files in the Papers window. It did not work because the folder was not identified by LEAP. I could not really understand what does it mean.

LEAP : On the right side of your screen, you can find 3 options (tag, ?, file) to bring a doc/folder in LEAP. I was thinking that by draging the pdf folder into this window ("file", LEAP would be able to recognize the folder containing the pdf files that I want to tag from the Papers window.

I don't recommend you to drag the Papers folder in the "file" (managed ?) : I found all the PDF files renamed in LEAP and of course no more associated PDF on Papers. CTRL-Z was not working to repair this bad operation !

Then I decided to select the files from LEAP, and to drag it in Papers ! At that time, all the classification was lost, and even I could read all the PDF, the author and journal list was lost. Then I had to identify one by one each pdf and the associated authors/journal/year ... (about 2000 pdf files) !

So please never try this operation, or read "how to use LEAP" before trying any operation with important documents !

Hope this comment will be helpful !

SCREENTOM  Great software. Great support. Thanks for the good job.

DONEBYLEE  I love Leap 2.beta and plan to purchase when 2 becomes official.

Only gripe is that I now wish I could REPLACE Finder with Leap. It would be great to have the Leap interface when I open folders and drives instead of Finder.

Oh well, I guess I will just have to retrain myself to always start in Leap. Unless someone knows of a way...???
