Question about the Circle pad

would it be possible for a future release of Citra to include an on-screen Circle Pad that can be manipulated with the mouse? certain games require ‘delicate’ operations with the circle pad that you can’t replicate with a keyboard (eg gently pushing the stick partially in one direction for tip-toeing)
is this something the dev team would be interested in adding? or am I just being stupid and this feature already exists somewhere?

You can connect a gamepad, you know.
