Hello,
Tabbles is a really great productivity tool for me and I use it a lot!

1. Improvement: after hitting ctrl-F for Find I regularly click "search again in tabble names".
Maybe you could link a second ctrl-F just to this function? I like to use the keyboard.

2. When I edit a document with word, this will create a temp file like "~$myfilename".
Maybe tabbles could optionally supress this kind of names?

3. vague idea
Do you know Evernote? I nice tool for capturing and organizing notes I have been using for 2 years.
And guess what? They also have their own tagging mechanism.
Sometimes I have to choose if a) I enter a short text into evernote and keep it organized there
or b) create a textfile and organize it within tabbles.

This would be a real goody if I could use my taggings for both tools from one "cockpit" (read user interface).

thanks
Andreas
