When configuring linked objects on the Admin menu, it’s very hard to find the right field because every single lookup opens first, and - unlike other parts of the product (report builder, rules engine, data designer) - they aren’t in order. So for example, when I was configuring the Opportunity as a linked object, I had to collapse about 15 lookups when I searched “Name” before finally being able to scroll down and find the actual field I wanted. Not a good experience.
