Let me start by saying I love this game to death, 100 hours in, no end in sight and I'm absolutely loving it. But, there are a few things with the ui and game mechanics that can detract from the experience somewhat. This is a list of little tweaks and enhancements I'd like to see that would make the game better in my opinion.
I know many or probably all of these have been mentioned before, but squeaky wheel gets the grease. The more discussion, the more likely it is to become reality.
1. Storage - yes been mentioned a million times. I like to hold on to cool relics, beast trophies, lore books and witcher armor sets. A step farther would be a display area of some kind for armor and weapons or just beast trophies if nothing else.
2. Make the action log last more than .1 of a nanosecond... or make a button or menu option to open the action log and scroll through it - preferably with clear separators between combat and non-combat actions, simple color coding maybe.
3. Option to disable the auto sheathing of Geralt's sword when he exits combat OR dramatically increase the active combat range. More than once an enemy has run just out of combat range and then immediately turned around and ran straight back at me, wolves and nekkers do this a lot. But Geralt, being the world class intellect he is, immediately sheathed his sword and walked around with the dodging ability of a tree stump until I pull his sword back out. Let me choose when to sheathe his sword, I have a hotkey for a reason... And does the enemy really have to be within like 2 meters of Geralt before he thinks its a threat and pulls out his weapon? Make him able to track and dodge enemies at greater distance, especially archers which you can't effectively dodge until you're practically close enough to touch nipples.
4. An autoloot option would be nice. I usually pick up everything anyway unless I'm overburdened.
5. Let us track more than one quest at a time. I don't like to fast travel much so I tend to go to an area and take care of everything going on over there, this involves a tedious process of checking each journal entry and then looking where it is on the map to see if its' close by... just let me track multiple quests, I can see what they are on mouse over already anyway. This would also imply an additional tab in the quest log for tracked quests.
6. On the same note, provide some filtering or sorting of some kind for the completed quests, either alphabetical or most recently completed first. Currently it seems they are just dropped into the list at random making it a real pain sometimes, especially late game, to find and read the completed quest journal entry.
7. Journal entry updates should also get marked with a star, not just brand new ones. For example, many characters get a huge number of updates to their character journal entries as the game progresses and currently there is no indicator of updated characters, only new ones, who knows how many updates I've missed.
8. Indicate whether a book has been read or not on it's hover tooltip.
9. Let us read books from the merchant window so we aren't going through 10 different menus and dialogs to read the book and then 10 more to go back and sell it.
Or just give us storage so I can keep a library of lore books. Another nice thing would be to be able to equip items from the merchant window too for the same reason. I just want to equip the new thing and sell the old one, this shouldn't require so much menu traversal.
10. Alchemy and crafting tabs need to remember the collapsed/expanded state of different categories when switching screens. This is especially bothersome when I'm crafting something at a merchant and I am going back and forth between his shop to buy some minor ingredients and the crafting window and I have to scroll all the way back down to the thing I am working on, or re-collapse everything, every single time I leave the screen.
11. An option to sort by level required for armors and weapons crafting interface would also be good.
12. Some more inventory sorting options like number held, weight, value. Also, books and manuscripts need to have their own tab separate from the food, potion bomb ect. tab.
13 .Let us put potions or bombs in the pocket slots too. I don't need a torch or Kiera's freaking lamp in my quick access radial menu during combat, I need more bombs and potions easily accessible. If only I could put them in my pockets too. It's not providing so many more that it would be over powering, I'd still have to make meaningful choices about which bombs or potions I want there and they could just be used the same way current pocket items are used - select from menu, then press quick access button. Currently for me, pocket items are very rarely used except for maybe the torch and it's mostly just wasting spaces on my radial menu.
14. More subtitle options - I often like to play with subtitles disabled because I have a bad habit of reading ahead by accident and all the suspense of the scene is spoiled moments before it happens onscreen. But I also don't speak Elvish or Nilfgaardian, and Zoltan can be a real pain to understand sometimes especially on the busy, noisy streets of Novigrad. So an intermediate subtitle option would be nice. enabling subtitles only for other languages and perhaps some harder to understand characters, Zoltan for example.
15. ui toggle button - Despite the downgrade that everyone goes on about, I find this game quite gorgeous, especially certain scenes like a sunrise over a misty forest. A button to hide the ui for a nice screenshot would be excellent.
16. In horse combat, make the side Geralt aims for the side I am looking at. Stop trying to auto lock enemies because when there is multiple enemies Geralt will just keep switching back and forth making it near impossible to swing at the correct guy sometimes.
Well, there you have it. Just a few ideas I've had. Maybe a few people will get to read this before it gets buried in the massive deluge that is this thread.
