Feels like I'm complaining again, but...
Is it possible for SQL editor windows to automatically detect when a file has been changed? I sometimes forget I have a file open, make a change in another instance and then find the older window again. If I'm being dim I'd continue making changes to that file, save and lose the stuff I made concurrently.
In contrast MSSQL pops up a dialog box saying the file has been changed giving you the option to reload it (or not if you want to keep a copy of the older file).
