Previously I never bothered asking for this as I assumed I was the only one with a dumb amount of items (I have 25 cones alone), but heard Nightmare and a few others asking for it as crates are quickly filling up inventories. Over time I think this'll become more of an issue as people get more items. I believe we're advising people to hold onto duplicates for future trading/crafting, so a scroll menu or even some form of Sort where useables appear at the top could be handy.
Adding on to the scroll bar, I think adding buttons capable of sorting the items in your inventory would be a nice quality of life update. Not sure how feasible that is right now though. +1 to scrollbar!
Realistically people are only going into their inventories to open crates and paint stuff, as far as I'm aware, so having these appear at the top would fix the issue I feel.
In terms of sorting the inventory; it's on my radar - however the way Derma works in Garrysmod is pretty shit and makes it incredibly awkward.
Could paints and crates be set to appear at the top of the inventory perhaps? Or some way to access them easier, I think it's the only issue really, when you buy a crate and have to find it within 200+ items.
What about this instead? https://dl.dropboxusercontent.com/u/11013411/ShareX/2016/09/2016-09-25_19-03-46.mp4
