dynamically assign an image?

[erwin]

If I have 5 different volume level icons and want to assign the icon most closely matching the current volume (probably by parsing pactl output) is this feasible with deckmaster right now?

I installed it, and have played with it a bit. The defaults are super interesting!

I saw that a command output can be assigned to a button, but can a buttons image be reassigned?

Or is there a API for adding new command types, and just writing the command in go instead of shell?
