A couple of things, and no huge rush on these but thought I would mention them.
First, I noticed some of the giftable games as inventory items don't have icons. I'm not sure if this is similar to the wishlist missing icons issue but I wonder if it is fixable. If you need links to people with a bunch of games in their inventory set to public I found a couple at random browsing reddit steamtrades.
This one has mostly games with icons but a few here and there don't have them.

And this next one seems to particularly have a lot of games as inventory items without proper icons and just the generic "Steam Gift" icon.

The other thing is sort of a feature request. On the inventory screen there are advanced filters. Well one of the categories is Games. That's all well and good but if you have a large amount of items in your inventory from many, many games it makes that filter header extremely long and unweildy and you have to scroll way,
way down to get to the actual items.
Screenshot of what I mean here:
And it scrolls down way, way, longer after that too.
If you hide the advanced options it doesn't remember the one(s) you checked so you have to leave advanced options visible for the filter to work. I'm wonder if there's some way the Games list can be hidden so I can just check cards or emoticons or whatever without having to scroll way the hell down to get to the inventory.
I don't know if new filter categories can even be added or not but it would also be nice if there were ones to filter just coupons or just giftable copies of games. Not sure why they didn't add those since those seem pretty obvious things you'd want to filter out in inventory, but it looks like they only made those advanced filters with cards in mind.
Now that I look at it better I guess they have two filter sections one being above for Coupons, Gifts (giftable games) or Community (Cards, emoticons etc) and then another subfilter on the side which further drills down those categories. Not the most intuitive UI in the world but they do allow to separate coupons from giftable games from cards. The subfilter list for "Games" under Community is still way too long though if you have a lot of stuff.
Hope that makes sense.
Anyway not a huge deal, just a couple of annoyances I came across.
