Really great addon! Are you planning on adding more features? I would like to suggest a function to remove tiles in build mode, perhaps something similar to the "s" cursor snap key (Perhaps "d" and a left click).

Also, you should post this to the Blender Artist forum if you haven't already!

Anyway, keep up the good work!

Thanks! Yes, more features will be added, my development tracker is over here but development might be slow over this week because of work.

I'm not so sure about adding a key for deleting faces. My general philosophy with developing Sprytile is to lean on Blender's workflow rather than coming up with new ones. For mass face deletion, I like using the paint selection tool to select the faces and deleting as usual but if there is demand for this, I might consider implementing it.

I haven't posted this to forums yet, I still need to do more promotion of the tool. Thanks for the idea of posting there!
