Yeah, I wish I could find time for many things. Unfortunately I'm not currently in a position where I can ignore money requirement.
It might be useful for people to create a space with wishlist items, or use the issues in tiddlyspace github repo, at least as a way of keeping track of stuff so it doesn't get forgotten or so if someone (e.g. me) comes upon some free time or good will they can pick something up.
Of course the problem with that plan is that currently the only evidence that tiddlyspace will continue living is that it has for the last two years. I'm not sure how much of a solid guarantee that is, but I guess I must have done something right putting the service together.
