Make this more like placing billboards while in editor. And maybe even make it so that there is an "assign gates" box where you can enter what timing gates that flagger is assigned to.
Finish flagger also able to wave a yellow flag.
Statues:
Set heights of statues while in editor. More precise than the slider bar that can be used for billboards.
Ability to select and move more than 1 statue at once.
Show name of currently selected statue.
Decals:
Show the name of currently selected decal.
Timing Gates:
A solution for split sections.

Thats all I have for now.
