Related records list having the added option to "Connect Existing" as well as the existing "Add New" option would clean up our current workflow so much. I hope this is on the roadmap soon. It seems like such an easy win.

Desperately needed.

This is a very important feature for us - we do a lot of linking! Right now having to use the Linked Records field in the same layout as a Related Records list is messy and redundant.

It would be great if the Related Records "search" box could work the way the Linked Records field does now: checking "+" next to a record adds the link and checking "-" removes it.

Thu I think I had submitted a similar request, but a lot more wordy! ;)
