I'm using Lumidesk to control some LED battens. They are Stairville LED RGD 252. I'm using the fixture already in the scan library "led bar rgb 252-10 ldl w rgb 001".
This has three RGB colour wheels, one control channel with presets to select the operating mode of the fixture and one speed control to control the speed of flashing.
When I patch this into a show I get two very large colour wheels at the top of the presets, with a smaller colour wheel underneath and the two other preset controls to the right of the smaller colour wheel.
The picture here shows the layout as it is.

The presets screen is so large that we have to scroll down the screen to access the bottom colour wheeel and the two preset controls.
What would be really useful would be a way of re-sizing and moving the controls around on the presets screen whilst programming takes place. For example in this particular fixture the would be nice to have the three colur wheels next to each other (across the screen) and the two other controls underneath them.
I've just tried creating my own ScanLibrary for the fixture and got the same results.
I'd guess that this fixture has more channels than most (11 DMX channels per fixture) so it may be something peculiar to this especially as there are three colour wheels but it would be good to know if a solution to this is possible. For example setting the size of the controls in the scan library.
