The API command view.replace always adds to the undo stack. However, it is useful for certain plugins to do a replace without actually adding to the undo stack. This will primarily be useful for collaborative editing plugins, where usually the other person's changes need to be replicated in your view, but each person keeps a separate undo stack (like in Google Docs).
It would be great if there was an option for file tabs to be placed at the bottom (or perhaps left / right too) of the window. The current paradigm of browsers prefers tabs on the top, but if your taskbar is at the bottom, it makes more sense for them to be closer to it. Opera has allowed such functionality for eons.
Congrats on your otherwise great product; I love the code "bird's eye"!

If indentation settings are "indent using spaces", then auto-indentation and the TAB key should insert spaces.
