I love the fact that VLC seems to be able to play and use most any media I throw at it.
I love that I can edit the play/toolbar stuff. Awesome.
I like the fact that VLC still has menus instead of trying to mash everything into a single menu "hamburger" ie like the browsers and some others have done. I'm skilled with a mouse and even I find "hamburgers" onerous to use.
I love the fact that VLCs icons are very simple, clean and clear what they do. I really like that they haven't changed much over time.
Most things seem to be where they should be.
I don't really see anything I wish was gone.
If someone that watches a lot of anime (or whatever) or something needs a special button or context menu added somewhere so they can enjoy VLC more, I'm totally fine with that and I'll likely infer the sense of it if it appears.
