Hello there!
Not sure if this has been suggested before or if it could be done, but I would like to suggest a scroll-able mouse option for the room editor. For example: if you click and hold the scroll button on your mouse you can drag and scroll the view of the room around in the editor rather than having to click the scroll bars on the side. I know the middle click is to copy room coordinates, but could implement another key such as the space bar or such to do the job.
This would speed up production time for me, and could aide other too.
Sorry if I come off sounding nit picky. :)
There's a similar suggestion here, maybe this is something that you also may be interested in: https://github.com/adventuregamestudio/ags/issues/613
Ah, yes! Exactly! Thank you CW!
