I really understand what you want to point out. You are right with saying just going through the textures alphabetical can make more sense, but I take a different approach (at least up to now, maybe someone can convince me to another way). I choose a planet (or area / module) I want to retexture, and as all the textures names have a suffix (LDA for Dantooine for example) all the textures for a particular module are nice packed together for me. And in that module retexturing I go through them one by one in alphabetical order, so I think I am not so far away from what you mean (I think). To the reused textures: As I see many textures, I often come to things and then "Oh hey, you have already done this textures for another module, or hey that's the same textures as xy just slightly, so I different colors, then I take the already remastered texture and modify it (I save all the textures as PSD so modifying for later purpose is easy.
