Another quick thought. Again, this program is already polished and excellent--I think "export" should be as simple as hitting ctrl/command-C with something selected and then pasting into a text file. This would be for quick little drawings without breaking flow in another file. Right now it seems like you have to export, choose a file name and location, open the new file, etc., etc.

And another quick thought. I haven't looked closely at your save format, but it'd be great if one could also have periodic autosave to *.txt or even autosave after every change. Layers, etc., would be lost, but I'd feel safer than leaving data in your "proprietary" format (which actually might be quite accessible) if I investigated it.

That's exactly how it works! Select any number of shapes, hit Cmd-C and it will copy them to the clipboard. You can even set a preference to include a comment tag when copying to the clipboard.

As a standard OS X document app, it autosaves are regular intervals that are determined by the OS (in particular, every time you leave the app, as well).

Ah, have to be in select mode. Not intuitive--I really did play around and give up, and I'm not stupid. ;-)

You actually can export a selection to the clipboard using command-c. I never use the export button, opting instead to select all with command-a then copy with command-c. Be sure to check out the clipboard tab in preferences. I find the option to trim trailing whitespace helpful, and the comment styles are useful to embed diagrams in source code.
