It should have been half-screen from the get-go. I think I just used
full-screen to make demos look nicer. Now that we have a CLI arg for the
screen mode we can make use of that in the demos.
This adds range select ability in two ways:
1) Sticky: like what we already have with the staging view i.e. press v then use arrow keys
2) Non-sticky: where you just use shift+up/down to expand the range
The state machine works like this:
(no range, press 'v') -> sticky range
(no range, press arrow) -> no range
(no range, press shift+arrow) -> nonsticky range
(sticky range, press 'v') -> no range
(sticky range, press arrow) -> sticky range
(sticky range, press shift+arrow) -> nonsticky range
(nonsticky range, press 'v') -> no range
(nonsticky range, press arrow) -> no range
(nonsticky range, press shift+arrow) -> nonsticky range
This also fixes a bug where after the rebase each commit in the commits view had a tick against it because we hadn't
refreshed the view since the base commit was no longer marked
I've been thinking about this for a while: I think it looks really cool if nuking your working tree
actually results in a nuke animation.
So I've added an opt-out config for it
