bookmark numeration

please make some kind of bookmark numeration for more comfortable use

The bookmark takes the name of the chapter by default (assuming it's provided in the audio file). It also overrides this if you enter a bookmark name so I don't think this matters much. You could type numbers instead and it will work the way you wanted. Having a counter to append to the chapter name would probably be better choice.
