Deleting buttons is easy, but not intuitive. Just move the focus to the button you want to delete by clicking on it (make sure the focus is on the button, not the text within the button), and press the ‘Delete’ key.

I haven’t figured out how to change the size of a button, but if you haven’t yet learned the IR codes, you can delete a button and replace it with a button of any size from the button gallery. After deleting a button, just select the button you want from the Gallery, click on the ‘Select” button, and hover the mouse cursor over the LCD configuration area. Wherever you click is where the button will be placed. When you add text to a new button in the main (home) panel, its entry will appear as a device on the left.
