When viewing a review, unchanged lines are elided. There’s a separator that says:
▲Show 20 Lines • Show All 91 Lines • ▼ Show 20 Line(s)
I have a hard time remembering whether ▲ means “show more lines from the block above the separator”, or “make the block below the separator expand up to show 20 more lines” - whether the triangle is pointing at the block to expand, or pointing in the direction that the expansion will happen.
I don’t have a really good answer. Stacking the three items
▲ Show 20 Lines
Show All 91 Lines
▼ Show 20 Line(s)
would make it less ambiguous, at the cost of vertical space. A stairstep presentation would be slightly less space, e.g. (but with half-steps so the total is two lines):
▲ Show 20 Lines Show All 91 Lines ▼ Show 20 Line(s)
View a difference with elided no-change lines.
I don’t seem to have access to a Config page, perhaps because I am a user and not an administrator. “arc version” wouldn’t run until I installed git, and then wouldn’t run unless I was in a git repository, and then claimed that I wasn’t in a git repository even though I was.
