I think these features doesn't exist in thindebug :

⬤ when paused in a loop structure (for, while, do, repeat...) having a key (like F8 or F5, but else) to run the script until it exits the loop then pauses again on the first instruction encountered outside the loop. (because sometimes you don't guess where it will exit and you won't manually scatter plenty breakpoints across your code.)
⬤ when in a loop (paused or not) having a key to set a breakpoint at the end (or the start) of the loop.

I think too that they can be handy.
