My suggestion is basically to reduce the amount of clicking, as getting to the material window requires first to click on the “Stats & Materials” button in your inventory and then again on the materials tab, which is annoying. This idea came to me after seeing the same was done with the profile button for S6 PTR.
The “Stats & Materials” button should also be split up into two buttons, making it a 1-click action to get to either stats or materials, and, arguably more importantly, eliminating this weird mash up of these two categories.
The current design choice has always struck me as very odd, as it makes little sense apart from being a place for another list. I never got used to it, and to this day and after being tempted by the glowing icon for new materials, I still look at the stats first before realising what it means and where to click.
Positive sideeffect is that this glowing icon also makes a little more sense to be where it is.
