You can customize MMM's look by changing toolbars buttons appearance. What you need is bitmap file, named mmm3glyphs.bmp, place to the same folder, where magic.exe is.
After restart, MMM will catch this icons set.

Please note that this feature will only work on full color systems

Bitmap requirements

Except of special name mmm3glyphs.bmp, there are few additional parameters for skin bitmap:
- height 15 pixels;
- each button image inside is of 16x15 size;
- so total width is 16*[number of buttons];
