@kirby see I really wish it didn't, the implementation itself functions and it's undeniably neat if niche and admittedly irrelevant to use nowadays unfortunately.
The lack of straightforward documentation, iffy implementation on things, insistence on donations/contributions and the staff's attitude are a real bummer. Seriously wish one could just self host it or contribute to it as OSS, I seriously think that modal could work out for that type of project.
Alas.
