The Lighting Controller

Hello, I know that the topic has already been discussed, but can not you actually add a background color change function in the program? Actually it looks like we were working on windows 98 ...
The present appearance is not very professional.

Our software presently uses native gadgets (tabs, drop down boxes, scroll bars, ...) which have to be available for both Windows and MacOS. This explains the present GUI. This will change for the next major software version (V9).

Thank for explain. I wait for v9.
