For a quick glance here is a video - Feature enhancement about selected clients on calendar view remains while switching to timeline view under appointments
We have a new feature enhancement under the Appointments page tab that will allow you to view the filtered clients under the Calendar View and maintain the same filters selected prior to appear under the Timeline View.
When you filter the clients under Calendar View and switch to the Timeline view page, the selected clients will remain filtered under the Timeline View page.

This goes vice-versa. By filtering clients under the Timeline View and switching tab to the Calendar View, you will be able to see the same filtered clients under the Calendar View as you did on the Timeline View.
