I’ll try it. Where can I find/download that?Unfortunately not. This app isn't hacking Elite Dangerous in any way; it's only sending key presses to the game the same way a keyboard would. That means you'd only have the ability to create buttons that map to keybindings that exist in game.
Having said that, I've had some users who decided to create a button that will look to the left in-game panel, go to the correct tab, and request docking. That works pretty well, but I do find it a little jarring. That's unfortunately the only way to automate that presently however.
