[Feature Request] unlock hardcoded keyboard shortcuts / allow adding duplicates #590

right now, one may not need all keyboard shortcuts that are offered:

in such case option to remove them would be welcome (for cleanup reasons only)

however, having an option to add duplicate shortcuts would be golden. for example:

as seen on example this would allow more flexibility with playback manipulation if one item could have multiple shortcuts by allowing duplicate items. (notice the Advance binds allowing jumps by 5, 10, 30 & 60s)

the extension default could be shipped with keyboard shortcuts as are set right now, with option for user to add (or remove) duplicate bindings. this would be appreciated especially by people sharing a device, where each person could have own set of shortcut preferences.
