Feature request: Add saving of multiple positions

[yrabbit]

This isn't a bug.
Is it possible to add multiple position memories? It's very inconvenient when, with audiobooks, you switch to another and the current position is lost.
Audiobooks are long, and finding the place you left off using the slider is practically impossible.

it required modding hiby binary which may not be possible by me. But sure I will look into it
