I'm glad you were able to customize the script to your liking, I even feel a little envious. ;-)
Is the version you have modified the latest updated by @o0netquik0o ?
A new version is already available that is ready to work even with the new version 20.2 and has also been designed to work with large screens (where there is more viewing space) and small screens (where everything is more tight).
The button bar of the simulator included in the game is hidden since it is replaced by the controls of the script itself, for my taste it is an unnecessary consumption of screen space but this is the personal taste of each player.
As for maintaining the same script with two versions of customization, it seems a bit complex to me, although I assume that the developer will be the one who can offer a more accurate answer.
