Hey there!

Great mod! Love the current customization options, but I figured a little small annoyance with the alignment of the bar.
Vanilla bar usually does not have it:
The bar is 1 pixel up the lowest Y:resolution, which results into clicking onto the field, rather than at any UI element.
If you can, you may want to move the bar just down a single pixel, and it would fix it.

Also tried it with all mods stripped off -> devtest, and this little offset seems to really come from your mod exclusively.

Edit: Window form is at fullscreen mode. So no overshooting mouse pointer padding possible.
