Yeah, I just have a set of scripts that I use for this; starting up the
UI in between iterations is too slow for me, so I don't diff there.

Yeah, but as you said, it's too much context. Seems like zero context or
all context are two extremes, where "some context" is actually the
useful point in between. If you're looking for something other than a
single bit flip (like an alpha tag, bank name, etc) then I'd expect
context would be quite useful.

That said, I really don't use (or plan to use) this, so if no context is
ideal for those that do, that's fine with me :)

Thanks!
