This is an excellent idea, it is a bit hard to use though. Some thoughts. I would prefer breakpoints to be disctinct from the current execution position. When thinking analogously to a debugger, Breakpoints indicate where the program should stop not where the program currently is, and consequently breakpoints can exist on multiple lines at once. I prefer a different graphic to indicate the active line. A line highlighted colour would be enough On my machine the area that is active for the 'line annotations' pop-up menu has no visual cue to say that it is there. It appears to crete a new 'line annotations' menu for each hover with the old menu lingering a short time before dissapearing, this looks quite odd. I have achieved multiple perminantly open 'line annotations' menus at the same time. It would be beneficial to have line ranges on annotations so you can higlight a block of code. Adding a new frame duplicating the current annotations would be good. Either that or have a way to declare the same annotation applies to multiple frames. Having the ability for an annotation to collapse a section of code to ... for within a single line or \n...\n for multi line collapse would let people focus on the code being explained.
