I haven't abandoned this mod, though my free time has been busy with updating/working on other mods and other related projects. I've found I'm most productive when I work on the things that interest me in the moment, as forcing myself to focus on one mod for an extended amount of time tends to burn me out for even longer afterward. When I have a large project, I usually have another large project to also work on that way I can bounce between the two whenever one starts being too exhausting. Now that I'm between things once more, I'll probably be picking this up again.
Sorry it's taken so long, I know there's a lot of people waiting for this mod to be updated. I can't give an exact time estimate, but if I ever give up on it (which won't happen) I'll be sure to let you all know. When I'm not actively working on it, I'm at least always thinking about it.
Ko-fi donations are certainly not necessary, but many thanks to those that have done so already.
