Pressing forward, I've added a few features to my custom map editor for my game.
* Better toolbar icons (for the meantime)
* Muti-tile select/paint
* Area/Layer Clear
* Layer VIew Toggling - Alpha blending support in wxWidgets is weak :-(
* Toggle view grid and tile indexing/numbers information
This will help me make maps for the game.
I've also started to use the excellent Inquisitor RMXP tileset.
Here's a couple of shots of a map I designed using that tileset and the new features I've added.
