Hi guys, Forwarding my answer to Mohamed here :)
First of all I am no expert in UI mirroring. What you did in the piece of code you sent looks find from a widget point of view. The remaining question in my view is what the best place to store that parameter (isRTL) is. My feeling is that it could be an option of the PigmentFrontend. What do you think of that?
