The good:
Character sheet looks much better, everything is easy to find now.
I like that some of the stuff I won't use on some characters can be removed from the bar (like shove, throw, dip and weapon attacks for spellcasters)
The bad:
Can't find a way to increase the size of the bar at all, this is going to be horrible in later levels especially for spellcasters and anyone who frequently uses items. Pretty sure we have even less space than before.
If I am going to be forced to have to click on extra buttons to open up more menus (spell slots, action, bonus action) then rearranging needs to be an option. Once my custom bar is filled up then I can see that I will be wasting more time finding what I need to click on than actually playing the game and this is stupid.
