When Affix Shards are in your inventory you can use the Store Crafting Items button to store them outside of your inventory and stash where they will be accessible to all characters you share your stash with (for example, Hardcore characters can’t access those found by non-Hardcore characters). Is this a feature you’ve been using?
If you’re intentionally not using this, could you tell us more about why? We’d be happy to look into making improvements here, but we’d like to better understand your use case.
The first time a new char picks up a shard or glyph a window pops up and says “You have picked up crafting material you can use to forge powerful gear. Right now it’s stored in your inventory” That window shows a button “open invemyory” that… err… opens the inventory. After clicking the next window pops up telling you “you can use the button ‘store crafting material’ to store them outside of your inventory and stash where they will be accessible to all characters you share your stash with”. Also the button might be highlighted. The popup will stay on the screen untill the player clicks that button.
Might be a little bit too much tutorial for this simple feature, but it’s overlooked soooooo many times
