Blurring lines between simple and regular commit modes

[danielchasehooper]

99% of the time I use simple mode to commit in Gitup. There there are those few times that I do need to switch out of simple mode to split work into multiple commits.

To do this I have to:

1. close the window
2. turn off simple mode
3. reopen the window
4. do the commit
5. close the window
6. turn on simple mode
7. reopen the window

Needless to say, it's a pain. It'd be really cool if the UI could be redesigned such that the difference between simple and not-simple mode are blurred, so that it's not really a different mode, so much as just special functionality in simple mode (one possibility: A button to unstage the selected file, and doing so would make the staging area appear).

At the bare minimum it would help to move the simple mode toggle from the settings window into the View menu and make toggling it not require closing and reopening the repo.
