It would be really neat (if it's possible to implement) if we could click on the power to directly activate it, as if we equipped it and then pressed "Z" key. I had that idea when I tried to use horse whistle from the wheel and it didn't come, then I realized it was only equipping and unequipping the power.
Also I haven't managed to activate items that use custom activation like Campfire furniture from the wheel. I guess those items use some special script so I'm not even sure if it's possible to implement it, but it would be awesome.
