When you wish to edit a data type entry it always opens with structure rolled up.
Would be nice to open with the select entry, rather than have to find and open it in the data type structure each time.
Likewise whenever you apply a change it rolls up the sturcture tree and closes where you were. This is really annoying when you have a large data structure to create.
Drag and drop/copy paste in a structure would be icing on the cake. If you are doing lots of things eg historian, scaling etc with similar parameters, or wish to change your structure then these features would save lots of time.
