Please add functionality for changing order of TArray elements in editor. I mean like arrow up and arrow down, just like in blueprint function parameters or in UE3. I feel really bad when I have to add Priority variable to every struct when I have array of structs.
I can’t belive this is not already there.
There is already a pull request of this feature: https://github.com/EpicGames/UnrealEngine/pull/2285, of course We have to wait till EPIC aprove it and merge into the engine.
Cool, oh come on epic, please merge that into 4.13 
You should probably extend your team and add some GitHub PR guys because there is so many awesome PRs which are already waiting for months
