This is so good, I hope I get to see it finished, someday. 

To the Developer, I saw mentioned in the comments you had MS, and wanted to say, be kind to yourself. I know from experience that it's all to easy to be frustrated all the time when you have a condition that limits you so much, but know that it doesn't mean you deserve any less kindness. I wish you well, regardless of whether this project gets finished someday.
