BrowncoatGR: Good idea and while they're at it they could fix the alchemy menu so it uses by default the most common ingredients or allows you to set preferred ingredients yourself
I've mentioned this a few times. It should default to the most plentiful ingredient if anything and if you choose to use something else it should remember the selection for next time.
Batches would be nice too.
Really, more categories and subcategories are what people want. Split everything where possible.
Swords: Silver/Steel/Misc (not that you should be carrying many)
Enhancements: Armor/Oils etc
Diagrams: Weapons/Potions/Oils/Bombs etc
Anything that can be separated is probably better off separated. Alphabetical sorting would be useful too.
The game is great already but it just needs a little bit of adjustment to make it fantastic in the usability category. Unlike most developers I think CDPR will take what we have to say on board (eventually).
