Map: marker icons to denote places saved and visited#374

Use colour and shape to denote which places have been saved to visit and which you have visited so that it is easy and accessible to work out the differences between them. When all places have the same marker, iyou need to rely on memory. Which has limits in place dense locations like London.

#58 and #102 are similar suggestions to this, which shows that it’s a feature that a large number of users think would be useful.

Great ; didn’t cross-check (but makes sense this is already in a backlog).
