Not much progress today, but I managed to continue with the Project I/O and make a little more progress. Firstly, I tackled a small bug in the Tabber initialisation code, which was causing the wrong Tabber to be activated (this involved popping the existing code into modular routines so that they can be called by the control routine and the I/O code).
While checking other parts of the I/O routine, I noticed that the Animation code fails to take into account what Tileset the animation is supposed to use; I'm in two minds whether or not to include this in the animation data, but it was added to the To Do list nevertheless.
