@pimoore In F, with groups you can put calendars together and then filter your view to only show that group. For example:

• I have different TIL and TIL-related calendars.
• I have put those together into a "TIL" group.
• So everything TIL-related can be seen instantly by switching to this view.

Over time, as I am able to better schedule more of TIL I'll probably make new TIL calendars that will then be split into different TIL groups depending on their use.
