Add a fullscreen or maximise button for source view

[eqrion]

When using iongraph to profile JIT code, it would be nice to be able to maximize the source view/bottom box. Right now it looks like it uses a horizontal splitter, and you have to manually expand it out. It kind of works if you are able to shrink the timeline view enough, but it's awkward.

Curious if this has come up before or if anyone has an alternative idea for improving this UX. I can probably implement a maximize button if folks are open to it.
