>IMO pagination is garbage UX, any sane GUI tookit can render more then 100 items on screen.

Well, I guess that's the web in 2020 in a nutshell, lol. What would you do with a list of 100,000 items? Just slowly scroll them out, one by one while your scroll gets faster and faster? At one point, are you just a billion pixels down? What does "scrolling up" even mean down there? Or do we just limit all lists to 1000 items, period?

It depends on the application, should we limit text editors to 1000 lines?

Should you limit the files in a folder to some number because the ListWidget has a limit of 1000 ?

No, the solution is too use our brain and realize that you can open giant log files in a text editor , you can have a list with many items in, this problem were solved already the issue is that HTML was designed for documents not applications and the built-in lists or tables are not optimized at all, where a List widget or DataGrid Widget in other toolkits were optimized.

I am not expecting a developer to put some hard work to fix this in his app, browsers or frameworks should do this, I dislike the idea that pagination is good UX as an excuse for "pagination is the cheap solution"
