Skillwheel (mod: Moonst@r)

Thought about it and decided to remove the version with the necromancer buttons. The visuals were terrible.

Cool mod, now it's easier for me to plan my build. True, it lags a bit when the hero levels up...

The mod is convenient for those who play in fullscreen mode, so they don't have to switch windows.
It also lags when you enter the hero menu. This is a problem with all mods that use a "wheel" interface. I thought it was because of my very old and weak computer.

Update: Changed the color and added borders to the icons in the "wheel". I also added the same borders to the icons on the level-up box.
