When autosave happens, there is no telling (like how it used to count down first) and it interrupts whatever you are doing, which is very abrupt and breaks the flow of work. It happens very often too, which makes all the more annoying.
It should instead wait for you to stop any action you are doing, then autosave (instead of stopping you, for example renaming a file, only to lose it in the folder you are in because it has some weird, unfinished name)
