Here's a small list of feature requests to change the way the buttons are displayed:
1. Right now the button grid grows and shrinks when the window is scaled to a different size. It would be nice if you could set a (customized) locked grid size (like 5x5, 9x9, 10x8, 4x3, 3x4, etc) and have the buttons scale with the size of the window. As it stands right now the biggest I can have the grid is a 10x8 due to the limitations of my 1080p display. I would love to be able to set a grid size to match the 9x9 layout of my launchpad.
2. Add an option to change the button colors. Have a different user-defined colors displayed when the button is active and inactive.
