Once upon a time seen the program for monitoring the activity at the computer, now can't find, wishlist are:
mostly interested in running programs, how much time spent in one way or another (i.e. what was in focus), and display tabs of chrome (just headings, no addresses, etc.).
Ideally, of course, more screenshots at specified intervals.
Tell me, what is it called? Free under Wine.
PS keyloggers, tracking file changes, etc., and unnecessary functionality is not necessary.
