Feature improvements for the "Map" visual in Real Time Dashboards

[clemensv]

[This is a personal wish for a project I am working on; trying to see whether there's similar community interest in this]

I'm looking for four distinct improvements in the "Map" visual for KQL:

1. Have the map emit its lat/lon corners (upper left, lower right) into parameter values so that I can restrict a query with them. I have a LOT of data in some dashboards and restricting by region would be very useful, so that the results in an adjacent visual track my restriction in the map, i.e. I zoom into an area and the list next to the map is constrained to what's in that area.
2. Have a setting that will keep the map at whatever position and zoom level the user did set it to, rather than the map resetting on refresh to include all items in the refreshed result set.
3. Have a tiny little tooltip on each bubble that is permanently visible so that I can, for instance, label a bus.
4. Have repeatability on which bubble for which item gets which color (and shape?)
