I really like the way Anki actually looks. A simple, but functional UI helps to staying focused on what your studying, instead of being distracted with so many colors and unnecessary elements on the screen.
Yes, whatever the look is or will change, someone will complain. It would be better to somewhat simplify some of the UI so not everything is exposed, though, for beginners.
Though I love Anki, I have to admit it is the ugliest software on my computer. I’m a really big visual learner so it took me 5 years before I could actually get into Anki and ignore how 2005 it feels.
