Expanding is the second last picture. If you enable it you can drag a shortcut to execute it repeatedly. Makes sense for undoing stuff.

COOL

Just had a thought, xpadder style bindable multi comands...

Example : Binding the weld tool and the nocollide tool to one tab on the menu like normal,
when the tool is selected you may then press a bindable key (In this example we hit h )
it then sends a command to use whatever combination of tool you have choosen then switches back to the gravity manipulator,
So again in this case it would send one command to weld once then nocollide the prop all in one go no extra tools needed as this would alow the use of creating macros for any tools you have.

another example would be to add presets like normal
(example tire speed 1000, hoverball keybinds, thruster force ect,
into radial macros, saying multiple sets of all yours tools and settings and even allow for simultanious multi tool usage through macros and more things i havent fleshed out yet.
i dont expect you to drop everything and code all this, its just a brainstorming idea for you to reflect upon.
I eagerly await Source 2 and the now confirmed VR Supported Gmod 2.
Hope GB_Radial ports well to source 2.
Thank you again for your time and efforts.
