Are you happy with the inventory/equipment manager? To me it feels totally clunky and slow. Dragging items from one character to another doesn't work smoothly, feels like I am dragging it by force. And I don't like the fact that you can't see the inventory and the equipment at the same time, it makes it hard to figure out sometimes who needs a piece of equipment and the character selection is also confusing so that you have to be careful which character is going to wear the new item. I found myself in a fight where my wizard could not cast because he was wearing by mistake a non proficient armor piece that was not meant for him.
I think that the menus work well enough, but I feel like I didn't try to use any menu other than the Character Sheet at first because it was too convenient (everything in one menu).
Despite the convenience, it isn't as easy to use as the other menus when managing equipment, items and spells for the party.
The Equipment menu shows equipment if you click on the empty slots, and if you hover over something, it tells you if you're proficient with it or not.
The Inventory menu is okay, but sometimes when I try dragging an item, it doesn't grab it.
The Spells menu is okay.
The Character Panels menu is okay, but I wish that the categories could be collapsed.
