Well, it seems I'm going to have to request aid from the DC folk.  Usually don't have to do that, 'cause my problems have typically already been broached and solved, but I don't seem to be able to lurk on this one.

I've spent the last few days searching, but to no avail.

A while back - say, two system rebuilds ago - I tried out a[nother] note-tracking app.  This one used a different approach than most I've seen.  There was a two-pane window.  The pane on the right listed the title of each note.  The pane on the left, however, did not list the usual tree ... instead it listed tags with checkboxes.  every time you checked one of the tags every note that had all of the checked tags was displayed in a list in the right pane.

For instance, check the tips tag and you'd see a listing of all notes with that tag; check the linux tag, and you'd see only the notes that had both tags; check the display driver tag and you'd see only the notes that had all three tags, probably only one or two notes, at most. 

It was a reasonably nice little app, but I didn't like the way tags were assigned - typed in each time, rather than accessed from a list - so I quit messing with it.  Don't even remember the name of it.

And that's the problem.  I've now encountered a support situation where that app would be ideal, free-form tag entry and all.  It has no learning curve to speak of, and it's fairly low in resource usage, if memory serves, so it can be left up in the background for near-instant access.  But I cannot, for the life of me, remember the name of the application.

I know it's on a hard drive here, but it takes a while to search through half a terabyte of files.  Even then, if the folder/file name doesn't jog a brain cell, I'll likely miss it.

So, cap in hand, I wonder if any of you DC folk might be familiar with this little app?
