Thanks for commenting. I didn't get into the details since 1: that would be the better in a blog post of its own, 2: I didn't think anyone would care what I think about some UI, 3: I could send in a patch myself if I was that keen on having it improved (which would seem the sensible thing to do if I keep on using it).

I guess UIs are to some degree a matter of taste, and a lot of what makes Anki's UI appalling to me stems from its cross-platformness (which is impressive technically though), which causes it not to blend in on any platform.

But there are a lot of simple unintuitiveness and inconsistency as well, like:

The "Deck Properties" is in the "Edit" menu, not the "Deck" one, while "Edit" is in the "Current" menu.

Main window Foreground color is set in the Display Properties (which, once opened, turns out to be called "Fonts & Colours"), but the background color is set in Preferences (in another "Fonts & Colours).

Preferences dialog has "OK" and "Cancel", Deck Properties has "Close", and Display Properties has neither.

I couldn't understand what "Hours to shift midnight: 4.0" meant, but "New day starts at: 4 am" would be immediately understandable.

In Advanced Scheduling, the Again options are in hours but the Interval options are in days, and you have to read the documentation to find that. Also, it's not obvious why the intervals are intervals (i.e. why you need both a Min and Max value).

And a lot of other small issues… might not seem like much, but it adds up to Anki having the worst UI out of all the software I use (closely followed by the gimp). It's still very good though, and really impressive software, please don't get me wrong on that…
