I might be getting senile in my old age but I thought that, like Basic4ppc, the B4A IDE used to showed breakpoint indicators by the vertical scrollbar. I seldom use breakpoints and Debug mode preferring logging and Msgbox debugging so I might have only just noticed that this is lacking in the new IDEs.
Why has it taken me all this time to notice this lack? Can it be added? On the rare occasion I do use breakpoints it can help to know where in the module any breakpoints are located to avoid an unexpected halt.
