I wish the web version of Keep was...faster. It takes too long to do some things, like deleting the tasks. And you can't even "wipe" a list. Well you can delete one, but what if it wasn't your last list? You can't even rearrange the lists in the order you want, which I find very frustrating.

I can't try it on the web ui right now, but I can definitely do all the things you just described from the android app.
