Excellent in every respect, but I have three minor quibbles:

1. I am sticking with 2.1 for now because being prompted for my password every single time I save a root-owned document during an edit is remarkably annoying. I can understand asking for the password once, but every time I hit the save button? Before see came along I used sudo to open the absolute path to the executable within the application bundle. This worked well, although it was not nearly as nice as see. But only having to authenticate once to edit the file was a significant advantage.

2. Why does a background appear on the screen with "non-commercial license" all the time? It is distracting. I don't mind if you want to make money off of commercial users, but embarrass-ware seems an odd way to do it. Genuine thieves won't be deterred, and legitimate non-commercial users experience a twinge of paranoia, guilt, or irritation, depending on their disposition.

3. To get syntax highlighting to work for zsh I have to manually edit the bash syntax file to include the suffix. That should be in there by default.

I still think an optional save button in the tool bar, even if it isn't there by default, would be nice.

Thanks for making this available for free to non-commercial users.
