1. Instead of putting every single spell, potion, and scroll into the hotbar, have "Potion", "Scroll", and "Spell" icons that open menus with the appropriate type. That is, you mouse over the "Potion" icon and a vertical menu of just potions appears. For spells, I'd want a menu of spell levels, and then sub-menus with spells of that level. And not just the icon but icon and name. I haven't memorized all those icons yet, and it's a PITA hunting for the one I want.
2. Find a reasonable way to prevent vendors from being looted of their magic items when you kill them. That's just cheesy.
3. Speaking of cheesy, it's too easy to take long rests, which undermines resource management. Need some way to gate that.

10. Instead of making rogue Sneak Attack a clickable ability, make it work like Repelling Blast or reactions: if the icon is activated, then the rogue will automatically use it whenever it's available. And then have some kind of alert (floating text?) so you know when it happens.
1. Agreed. The hotbar should be used for abilities we use often (that we manually put on the hotbar), but menus should be the default way of finding everything. The hotbar system will be a complete mess when spellcasters have ~20 prepared spells (15 prepared+5 cantrips) at level 10. Plus the many other abilities/items/etc that will go there.
2. Agreed. Vendors sould have guards corresponding to the value of loot they own, or be powerful themselves and use the items against you as @RagnarokCzD said. It's a bit dumb that you can easily kill a low-level vendor and get tons of valuable loot. I'll expand this to pickpocketing; each vendor should keep their most valuable wares in a chest with a much higher DC.
3. Yes.
10. Yes. If I miss my initial main-hand sneak attack, I should be able to attempt to sneak attack with my off-hand. Also sneak attack should activate on AoOs.
