If you are new here, or you are used to the old guitarscientist.com/generator, it's a good idea to start with the SIMPLIFIED interface.
If you need more than the basic functions, but you often wonder "Where is the button I'm looking for? ", try the LARGE option.
If you are a fast learner, or you already know this editor, then the COMPACT option is still the default.
1) Click on the MENU ☰ icon in the top left of the screen, right next to the logo.
2) Move your cursor on "Interface mode..."
3) Select your option from the list.
You can switch interfaces while you are working on a diagram as many times as you want.
The editor will remember your choice and you will only need to do this if you want to change interface.
