Hide empty groups

I am doing a lot of genealogy / family tree work just now in Aeon (will share some of this in due course). It is throwing up some challenges so will be making a few feature requests. Here is the first…

Can we have an option (in the Filter menu?) to hide any empty groups?

For example in this Events timeline view i am grouping by Person. I have a filter applied though to only show events for people on my direct family line. This results in a whole load of empty groups that I simply do not need to see. The image below is a small snippet. I have around 800 people in the timeline of which maybe 700 are excluded with my filter. All 800 groups however are still shown.
