StarUI Inventory improves all inventory screens for use on a PC. Compact display style. More details in sortable columns. Item category icons. Category as left sidebar. Many quality of life features!
For anyone who hasn't yet checked out the Nexus since the game's release, an inventory UI replacement mod has already been out for some days. It gives you a way more compact and useful inventory interface with clickable columns that you can sort by, and most importantly the value per mass column. The most important item stat in Bethesda games.
Another thing you can do is add temporary columns of many different stats to compare your items. It also shows that quantity of an item you already have while shoping. And probably other things.
You can install mods for the Game Pass version, the exe is different so the script extender doesn't work but StarUI doesn't use the script extender. I have 4 or 5 mods installed via Vortex right now for Starfield Game Pass version.
I would try to walk you through how to set it up but it was so seamless and basic I don't even remember. Just install Vortex and point it to your Starfield/Content directory... on whatever drive you told Game Pass to install the game on.
When you install a game with Game Pass you can tell it what drive to install to. I think by default it might just install to your windows system drive but you can toggle that option in tho settings.
I installed Starfield to my F drive so it's installed into something like: F:/XboxGames/Starfield. I then installed Vortex. Vortex did not automatically detect it but I just hit the button to manage it manually and directed Vortex to my F:/XboxGames/Starfield/Content directory... then it picked it up and I can install and deploy mods to it just like I can Skyrim or Fallout (which I have through Steam)
I use NileSoft Shell, a replacement for the stock Windows right click menu that adds the option to give you permission to a folder with 2 clicks. Worth it for GamePass mods.
That's not the case. The game folder is accessible... Game pass has been doing that at least since its had Bethesda games on the service.
That being said, the exe is technically different from Steam so the script extender doesn't work. Not actually a big issue this early in the mod scene (most mods don't use the script extender yet). That won't be the case forever unfortunately.
