Thanks for the quick response! I will make sure to post it there as well.
And the Fill tool is what I use at the moment, but that's not quite what I meant, sorry if I wasn't clear on that... I'm talking about a tool that will change all of the selected color on the texture to the color you have picked. For example, if there are orange pixels scattered around, clicking on one of them would replace all of the orange pixels in the editor with your selected color. The fill tool somewhat works as this, but you still have to select each spot where they are not connected. (This can be problematic when editing larger patterns and sprites)
Also, would this go under the Support or General discussion page? Again, thanks for responding so quickly, I'm having fun with this program!
