On a technical level: I agree, it works great. Their dashboard needs some work. What I find annoying is mostly the "load everything in single ajax requests, but don't set the size of it in HTML", which makes elements jump around while stuff above them is being rendered. That's very annoying when your connection isn't great for some reason and buttons get replaced by different buttons. I get it, "use the API", but when you need to do something manually, I'd prefer a higher total load time over something that's asking for mistakes. There's a good reason Google is heavily advising to get rid of layout shifts.

The other thing I took personally was them removing the "remember me" functionality in a two step process: first it was broken, and then they removed the feature alltogether it instead of fixing.
