Started tackling a routine which I'd been meaning to finish for quite some time: the ability to view a layer as decimal or hex (as opposed to tiles). The main reason this was put on hold was due to processing power - Blitz seems to stumble when a huge amount of text is being printed on screen (which is often the case when in 16x16 tile mode), or when drawing a lot of rectangles.
I decided to get around this by a) not drawing a rectangle around each tile, instead just drawing a grid over the entire screen, and b) only printing text in 32x32 tile mode or greater - 16x16 tile mode would use a specially created tileset.
With the core of the routine written, all that remains is to finish the special 16x16 tileset. The final task of the night involved tracking down a bug which meant that the editor wasn't starting up properly when New Project was selected; after nearly an hour of tweaking and bypassing code, I found the culprit: a Return command in the wrong place. Gah!
