I will be putting all of my art into spritesheets packed with multiple sprites. For example, I will have a spritesheet with 8+ swords on it. Is there a way to display only the part of that spritesheet that has the sword image I want? This would require a size and an offset variable, i.e. 

Offset: 16, 16
Size: 16, 32

If this isn't already available, is it planned? This is fairly essential for my project.

Thanks!

This seems to be one feature that CastleDB has over this software. Other than that, this software seems incredibly useful!
