Store map.features in tinydb

Hi Steve.
You post will be helpfull with other screen, which will record the track done by the user. Great!
I have another question related to this project, about how to work with markers created in runtime using “Call map1.createmarker”…

If i want to, for example, delete any marker that has a specific Title… how to do it?
Or if a want to modify the description of a specific marker, without selecting it from the map, but searching the marker by the title it has… how to do it?

Regards,

Patricio
