In QGIS 3 Welcome page when I right click a project a tiny context menu with 'pin to list' rsp. 'unpin from list' as first entry appears.
'pin to list' produces a little pin near the project name and 'unpin from list' removes the pin:
I consulted the documentation but I could not figure out the deeper sense of these pins.
Does somebody know what these pins are for? Perhaps some kind of favourite projects?
