I think instead of having a search box on the upgrade list which is not entirely filtering as expected a dropdown menu with checkboxes would be nice to select the raid tier and the difficulty levels you are intrested in.
I am not entirely intrested in mythic Tomb of Sargeras when there is still a lot of upgrades for the guild in heroic mode.
If the personal gear upgrades are close to 0 in a specific level,even with a chance for forged gear, or if you use team optimizer for the raid group, you can still reccomend to try a higher level.
For dungeons it would be nice if you could include the multiple tier levels so that you can decide which m+ dungeon to run this week primarily and below which treshold level you shouldn’t waste your time trying to find a group.
Your reccomended M+ dungeonlevel is +13 (as your lowest item is 895) , you should do arway.
Something like that.
