As per usual, any bug reports or feedback is greatly appreciated. Soon I'll be sharing some higher priority to-do list items to decide on (get motivation for) what to work on next. This should have been 2 separate updates instead but I've been a bit distracted over the summer. The next update shouldn't take nearly as long as this one.
