I would suggest you guys to solve at least two things in SA2:
1) Preferences/Setup: when I change my library ExtJS path reference, press save, this settings should be available to all projects - I don't like when create a new project, the path reference comes up with the old settings.
2) History manager: I don't know how you guys should solve this, but at a minimum automatic multi level file backups, file differencing and restore it would be nice in SA. e.g. a directory _history in the project.
3) code completion on-the-fly (similar to intellisense) is nice;
