So, this is something that is an irritant more than anything else...
In the plant schedule, the "Trees" have their container sizes listed under "Cont" which I know means container size. Others might not know this, especially a plan checker.
The "Shrubs" has the container sizes listed under "Size" which seems much more common and self explanatory!
Then we come back again to "Groundcovers" and it reverts back to "Cont".... Why not make this consistent and just have "SIZE"? Seems more self explanatory and keeps things uniform in the schedule!
