As a casual user, I find the UI incredibly confusing. And not just because it's different from GitHub, but because there are so many features and there are menus absolutely everywhere.

I'm sure if I used it more often that I would figure it out, but it's deeply off-putting for someone who only uses it twice a year or so.

The really bad:

UI is constantly inconsistent. You have to keep reloading the page to hope to see what’s up with your MR. Doesn’t help it’s super slow to load.

The backend infra is super unreliable, with actions failing to start, merge trains being stuck, their webhooks being overloaded.
