I wonder, what's the correct solution for this ? Because so many apps I use including browser are definitely "not responding" multiple times per day for various reasons (full ram, internet stall, etc.)
To be fair, reading the terminal is a completely different beast from reading a GUI. In addition to building a static view of the screen for review, you have to handle dynamic updates (auto read). Cursor movement tracking, figuring out when to read what, when not to read (an f just appeared on my screen, but I just typed the letter f; if key echo is turned off, I don't want to hear "f"). If a line was just added, it should be read, but if my cursor was moved to a different line, I want to hear the line it moved to, but not if that line was just read because it just appeared. All sorts of rules you sort of discover as you go. But the one thing you definitely don't want is for any new change to interrupt what was already being read, and that's exactly what VoiceOver does.
I do my best to make my apps accessible, so feedback like this helps.
