Request: Add keyboard/mouse shortcuts for back/forward

[Araraura]

Can shortcuts for back/forward be added to this plugin? Specifically I would like to see support for mouse4/5 buttons, so that when the filesystem is highlighted and those buttons are pressed, it would move forwards/backwards in the folder history.

it's a good idea and can speed up the workflow in certain cases, unfortunately I ran into problems when trying to edit the file system (it was very difficult to make it not crash), I think it can be implemented, the same like shortcut feature in #5 and #6 , but I haven't tried it yet because there are some quite critical fixes that I want to push first, sorry for taking so long to respond!

I'll try again, but no guarantee, I also welcome PRs if anyone wants to implement it
