While it is natural a selected stash tab is being highlighted, the case with the stashes themselves seems opposite to this intuitive logic. As we can see it on the picture above, the first selected stash tab in a row of 5 is highlighted and other four are grayed out. It is the personal stash that selected, but the shared one is glowing much brighter instead. I think it should be grayed out too. It’s up to devs for colors and such, but these two cases must be aligned to get rid of confusion.
EDIT: 22.214.171.124 fixed it. Thanks, Crate!
