Spent the afternoon striking even more tasks from the dreaded To-Do list; firstly, I made a couple of changes to the Export menu, allowing specific combinations of Layers (current, visible, or all) to be exported as a BMP. Previously, only the current Layer was exported as a BMP image, which was more than a little restrictive.
Next came a change to the Layer menu, with the option to view just the current Layer, all Layers, or no Layers (the reason for these might not be readily apparent, but after using the Editor at length I was finding their absence more and more annoying).
Next came more tweaks to the Brush thumbnail system, which ensured that only the current Brush is affected by the "Regen" button. Whilst knee-deep in this particular chunk of code, I also added the regenerate current option to the Brush menu (along with a "regenerate all" option, for consistency). And in a similar vein, I also added the option to clear the current Brush or clear all Brushes.
