I agree that picking up an item and miss locking leading the character to move happens alot.
Maybe some customizable item label size would help.
This is a very hot discussed topic and is not as simple as just adding it.
Also shards are not unlimited.
If you play one single character alot or do play alot of characters on normal mode, you will acuumulate lots of shards up to a point, where they don’t matter anymore.
This will most likely change a little bit, once we have regular cycles and resets.
But Mox (the Game Director) already stated, that the devs are aware of having excess shards is very common and they thing about possible systems that could be used for that.
If you are interested here is a thread about auto pickup:
I am not entirely sure what you mean.
You can already search for affixes or item names. At least in the stash.
Altough having more search functionality would be nice.
Like searching multiple keywords at once to only show item that have all of them.
