I wouldn’t have thought it several years ago, but I’ve actually been hacking on some Javascript, for Stuff to Do. My immediate need was to make the system work better with IE6, which had problems with the previous way of doing things, which involved big updates to large portions of the page. Now, with Javascript, I do most of the work that way, and rails only has to make note of the new task priorities in the database.
In terms of UI changes, I also flattened the task boxes down just a bit, something that a user requested.
Hopefully it’s reasonably stable, as I will have very, very little hacking time until we are unpacked in our new place in Innsbruck!
