> A lot of the lists (UL) break for many of the libs in the demos, including pico
Unordered lists look okay to me[0], but it's possible that you are referring to the navigation section at the top of the page which technically contains a UL as well. This is just a boilerplate HTML5 template[1] with Pico CSS applied on top, so it seems that Pico doesn't have special handling for this particular usage of ULs nested in NAV elements (some frameworks turn these lists into a navigation bar or even dropdown menus, but it's interesting to compare how each of them works out of the box).
> the cursor remains "default" instead of switching to "text selection" when you hover over text
This is directly from Pico CSS itself -- check out the homepage[2] and you will see that the same thing happens there as well.
