I would find it handy to be able to occasionally add a keyword,
person, or location directly from the viewer by typing something like:

	^K Party
	^P Nicolas
	^L Paris

Ideally with automatic completion.

Also, the token mechanism could possibly be merged in the standard
category mechanism, using user-modifiable keybindings like:

	P: set Keyword Party
	p: unset Keyword Party

This would allow for new possible user's workflows, without changing
the existing ones (for backward compatibility, there could still be a
Token category and a bunch of default keybindings P -> set Token P).

Just suggestions ...

By the way: I am really looking forward the video support! Thanks so
much Jesper for working on that!

Best regards,
