I couldn't get ctrl+h or history view (for menu) to work. It looked like ignored (but see further) 2. I tried to remove the Mapillary layer, but it start to re-add itself. Maybe it was due to the fact, that download of mapillary images took some time 3. When I finally succeeded in removal of Mapillary layer, all overdue history dialogs appeared at once. 4. When I readded the Mapillary layer and later removed it, a livelock happened.
