No date-separation in the watch-list.
It's really annoying, because it just turns everything into a jumbled mess. On FA, I used it to keep things reasonably organised, in a strange way.
As in, I don't like faving everything. My watch list there is a distillate form of timeless favourites!

The icons are small.
Yea, it's kinda easy to miss click or something. Sucks!

There's no buttons on the top.
I dunno why, but that's super weird. Vertical symmetry is super useful sometimes, dudes.

The topbar is empty.
I dunno, just feels kinda lonely when it's this big, empty abyss. And it feels like the devil is staring at me.

Watched people.
I highly doubt I can rewatch everyone without a hassle. I have 3000 watched folk, and that program people keep recommending doesn't work well enough.

Thumbnails.
I rather liked FA's 'no thumbnail' policy. Seeing the full image straight up in my watch list meant that I couldn't be deceived and just see it. This start, static 'size' is bugging me. It makes it all feel so... samey.

On the other hand, there's a lot less drama over here.
Tough call.
