I would love to have a checkbox that would allow the re-coloring or add a colored dot to items in the inventory that matches the loot filter coloring. I sometimes find I need drop items from my inventory on the ground to see the corresponding loot filter color. This would help me remember why I thought something was important.
This… I have so many stash tabs that the quickest way to sort everything else is to enable a “special” loot filter, dump everything on the ground and then pick up “matching” items to put them back in the now sorted stash.
