Hi Alex!
I’m really sorry to hear that you feel that way about Filter Bar. Let me try to help you with what you are trying to accomplish.
By default, the plugin comes with many built in filters that you can add/remove and configure to suit your needs > https://theeventscalendar.com/knowledgebase/configuring-filter-bar/
If you want to create some custom filters you can do so, but would require some custom coding, which we cannot support due to our terms > https://theeventscalendar.com/knowledgebase/what-support-is-provided-for-license-holders/
That said, we always like helping out and at least point you into the right direction as much possible.
We have a great article that explains how you can create custom filters > https://theeventscalendar.com/knowledgebase/creating-custom-filters-for-filter-bar/.
Could you please let me know more about what custom filters you need to create?
Please let me know about it and I will try to come up with a code snippet to get you started and point you in the right direction as best I can.
Best regards,
Victor
