great, but next time please wait a bit for the answer from more people ;)
This mirror feature was done by me, so I feel I kinda own/maintain it
and I want to be
able to share my view on it too.

Anyway I like the idea!

Just a question: will it be disabled when the user select some tool
that does not
have a sense to be mirrored? e.g. gradient tool, assistent tools,
making selection etc.
(that might give a sense though in same cases)

Cheers
