Looks exciting! Gotta remember to keep updating OpenStreetMaps!

Because you mentioned taking notes and manual tracking, maybe a note taking or wiki application like Obsidian with its plugins.

How ironic that much of Microsoft and all MacOS depends on Linux/Unix.

I mean ironic for those companies. Irony is not directed at OP.
