This add-on provides groups of action buttons. In actual, there are 3 groups of buttons you can create. To use this add-on you DO NOT need logitech G-15 keyboard or any other special stuff. This is just bar mod which happens to have a default setup to look like the G15 macro keys.
So why the name is G15 Buttons ? Because of, the idea has come related to my new G-15 keyboard

And button groups are optimized for the keyboard. But also you can change all the settings via options form.
You can create upto 24 buttons per group and can change starting id of buttons. You can also change the row count, offset, scale and someother options. You can create a group of buttons and move it where ever you want. You can change all the parameters with options dialog (/g15).
Also you can bind keys (any key, even normal keyboard keys

via 'Key Bindings' in-game menu.
