1 and 6 are PC exclusive. As far as I know, you can’t expand chat history on consoles, or the icon is just present on console build whereas it was overlooked on PC.
As for 4, could you take a look at Gear -> Packs -> Buy new pack and see if Uncommon Loot Pack is the last one listed? If it is, then the ordering is broken (it doesn’t even follow the alphabet, since “UPR” should be after “Uncommon”). Compare it with screenshots at 21 interface issues (with lots of pictures)
As for 5, it’s also explained in the topic linked above. Let’s go to Command menu yet again and agree on some naming:
Sub-tabs (visible if given tab is active):
- Loot Packs
Now, the issue is this: if you select Gear or Career tabs, then their sub-tabs appear right below the selected tab. But for Marketplace, the sub-tabs appear under the space between Gear and Career instead of below Marketplace.
The fact that 2 and 3 are not “shocking” to you doesn’t mean there’s no issue. The interface is objectively not consistent within itself, there’s no subjectivity here.
But really, all your questions would be answered if you just read that topic. I think I’m done repeating myself here, sorry.
