Here's a
post where I described the steps to creating a new Dashboard .exe
To start with, just try deleting the front panel controls you don't want.
You can delete from the front panel, but remember to remove the broken wires from the block diagram afterwards.
Test after each deletion to be sure that what you are doing works and hasn't been broken.
You can repurpose some of them to be your boolean indicators too if you want.
Once you've removed what you don't want, then you'll be able to see what code is no longer needed and can proceed to remove some of that. But do it all a step at a time to catch and train yourself not to break the program inadvertently.
