First of all, love this software, and am current working on making a Metroid Plus 3dn file, and am enjoying the process quite a bit! Although, I'm not sure if this is the place to ask questions, but could there perhaps be a 'replace color' tool added to the texture editor? The majority of my workload is spent erasing all but one color on a sprite, but with the current setup, I usually have to click on each individual pixel in order to clear them out, which can be rather time consuming. A color replacement tool would work wonders for this sort of thing, and cut my workload substantially...
Still, love this software though, and I would just like to know if this sort of thing could possibly be added in a later build. Looking forward to seeing what is added later on!
