Anyone can upload the latest image... Though 4.0 is not yet released.
Actions are executed, if condition is true, and hitcount reached.
IIRC (but needs to be tested for all backends) hitcount increases, if condition is true.
Auto-continue issues a "run/F9" when the time is over (during that time, the user can press pause in the IDE / may be backend dependent).
And as said, the IDE does not take focus.
Disabling "break" is similar to auto continue. Except, the time is just what it takes to perform any other selected actions. And it does not go to run (at least not in all backends), it can instead also continue a single step. (IIRC)
Not sure what your last question refers to. The word "activate" is not mentioned with auto continue?
