With the scripting/macro thing up and running, a user could simply make things like open and close into actions. In fact, first thing I'd do would be to record a lot of your tutorials.

Something closer to a circular kernel would be a real boon.

I really need to try out the latest version I have in Windows. I've been running it with WINE, which has some issues, but memory management seems better. Last time I tried running it in Windows(version 1.seventy-something), an 8k x 4k would crash the program pretty promptly. The latest version, in WINE, was stable with an 8k x 4k on board. Incise Flow and river finding was pretty slow, but it did it. I'm hoping the difference is in the program and not some quirk of XP(like being able to resize windows…).

And let me nth the thanks for posting those tutorials. You have a few others strewn about the site that would be worth linking to.
