I understand the problem. If it’s biting you, it should be taken seriously, but
I have a quibble. Xcode draws a line across the stack trace where frames are
elided; and it provides a slider at the bottom of the Debug navigator to
control how aggressive the elision is. It’s not obvious, but it isn’t hidden.
There’s a tradeoff between making the feature self-documenting and keeping it
from being so blatant that it distracts from the principal content of the view.
Self-documentation of something that can’t be explained briefly, and is very
peripheral _once you know about it,_ is Hard. Making the line solid and three
points wide, instead of dotted and one point, wouldn’t be enough.
But people miss the feature as currently implemented, it can be mislead them,
and it can waste their time — as it wasted yours. I’m not saying you’re wrong,
or that Apple shouldn’t spend resources on solving the problem, but it is a
problem to which I see no easy solution. (And anyway, the current system is
lucrative for me.)
