Tooltips not clear
This is based on the current beta and I'm aware that it is an interim state and sharing features are not finished yet. However, this nevertheless seems important because it's about very basic UX
--> Should be rather "Display shared Timelines" and "Display my Timelines"
To me it's still unclear of "my" Timelines, which I share with others would be displayed as "my Timelines" or as "shared Timelines". I think we need to be very specific here to make the differences very clear. See also my comment here: #1217 (closed)
