It is now officially released, and it's a major update too.
I have now added a new tab in the "dock settings" menu.
It's called "ShaderEffects" and will use the graphics card to add some effects to icons when you enter one.
There is also another option in the "general tab" which allow to set new behavior to SliderDock when unhidding it.
For example it is now possible to make SldierDock appear right under your mouse.
And I finally fixed the icons being cut when SliderDock size is changed.
This happened due to some screen having different DPI and c#3.5 trying to be DPI independent.
That's also why most user never got this bug.
there's some new icon background too and a lot more.
To know all the changes you can go to the change log page like always.
