Here are some of my suggestions:


UI Changes:
- a quicksave button would be nice
- make the default buttons for save/load farther apart (so you don't accidentally save (F9) when you meant to load (F10), for example)
- when you open inventory, it should go to the last tab that was open - so if i want to read 5 books in a row, it would be nice if i didn't have to go to inventory -> click misc tab every time, i could just hit inventory.
- make closing book return you to the inventory screen, not out of menu entirely
- a sorting button for your inventory might be nice - group items by type (limbs, ores, gems, herbs, potions, enchantments). The Witcher does this, and it's wonderful.
- toggle-able option to turn on or off a numberical cooldown countdown over your skills? Some WoW UI mods do this, it was really convenient
- ability to name self-placed map markers
- small portraits for health/mana information of your summons, so you can keep track of how soon they're going to die

Gameplay Changes:
- Should platform operators have direct access to your stash? It is annoying to have to move 30+ items from stash to inventory just so you can visit your alchemist + enchanter.
- Would it be possible to view potion/enchant recipes in your logbook, after you've collected them? this way, it would be easy to reference what ingredients you need right when you're in the field, instead of having to travel back to your tower to figure out if you needed the venom or the ginger...

that's all i can think of for now, hope you find some of these helpful! <3
