I have seen a few of these posted here, but will reiterate since they are still relevant.
-
Auto publish after a merge has completed when initiated from 1-click publish.
-
A visual signifier or auto-selection (or dont even show the item) when you are the only one who has touched it since last publish. Large merges are very painful and troublesome when you have just finished changing 40+ things, and your coworker has as well. Even knowing that you havent worked on the same things, you still have to dig through and check every single thing they touched, and this can cause a lot of unintentional overwrites.
-
A "Select last modified for all" option. This applies to us 98% of the time.
-
Increase the default serialization amount in the IDE config past 65k. We publish quite a bit, and after a certain point are not able to push the merge with published button to merge because of IDE errors.
