best event merge extension for sure, but is there any way to not have the blue background behind the weekends. its really ugly to me, and clashes heavily with my event colours. especially when i already have an extension that shades days, but its hidden underneath this extensions weekend colour.

Seriously don't know how I'd live without this extension - it turns a stressfully-cluttered calendar into a work of art, with lovely ombre effect. Team was super responsive when I posted an issue on GitHub. Grateful for y'all's work!
