You can open the bridge app from the top bar , then open the fab app from the drawer , Now while you can’t dl anymore form the bridge app you can still search item id tags there and bring up a pic of what you’re looking for.
Then look at the fab app and match up the thumbnails.
So say you’re looking for a certain boulder and you have the item id , punch it into the bridge plugin , do the search and find it.
Then switch to the fab app and get to the rock and stone subsection and compare pics till you find the boulder you were looking for on fab and add to project/library.
Not the perfect fix/answer to lack of a item search feature in fab but it’s a nice little workaround I found on accident. (accidently opened both browsers lol).
