I think you’d get much clearer answers about use-cases from reading (or asking in) the Tinderbox Forum.
Tinderbox is one of those apps that can be a godsend to the right people. It’s one of those apps I’ve looked at periodically, every couple of years, trying to see if it could be useful to me and if it got any better looking or less confusing… and I ended up each time quietly backing away from it, and skipping far, far away.
Eastgate has a page for a public file exchange showing a variety of sample Tinderbox examples that could spark some ideas for you. To me, the fact that the examples are all 9-14 years old is all too telling, however.
