Filter bar for Events Calendar

Hello,

I bought the filter bar plugin and realize the customization options are a lot more limited than I could ever imagine. The ajax function at least filters but you cannot at all control what the parameters should be without deep customization. I hope to be proven wrong.

So, for this page I have but one issue left; I need to remove monday and tuesday from the filter, maybe even wednesday. One would think you cannot filter on days where there are no events, but there is no way to hide empty filters or change name of the days, nothing.

Has anyone tried, and succeeded, at editing the filter check boxes and its content? Can someone point me in the right direction if this is something I have to fix myself?

Thanks!
