Favourite cities marked on map

As per attached image, favourite locations on the maps are toggle to remove when I press on my mouse left button temporarily.
Sometimes, favourite locations are needed and not necessary to view some times.
Can you add a toggle button on screen? If you can, please add toggle button for PC(windows) users, thanks.

We will consider it, thank you. It is not currently designed for that many favorite locations.
