Hey @Ultraviolet,
Thank you for your post 
- I hear where you’re coming from and will certainly share this feedback with our internal team. I apologise for the setback That said, if it’s of interest you can achieve this via our Google Calendar and Outlook integration. I will leave the support links below:
- In terms of calendar filters, had you explored our quick and advanced filtering options via the calendar view: The Board Filters
- This is a feature that is on our long term roadmap - you can check it out here → Customize calendar widget colors - #15 by BDavis. Stay tuned for future updates!
Let me know if you have any questions!
