Lodestones and the new navigation bar UI in 1.21.7

 I feel like it would be very intuitive if you could set a lodestone down, which would in turn set down/place a location indicator/marker on the new navigation UI bar, there could be a menu where you can set the properties of the location indicator, maybe you could click on the lodestone and set a color (using a dye maybe?) or a specific shape (cross, star, circle, square) so you could differentiate between various lodestones you have placed down.

The F3 debug screen on vanilla is just too overstimulating sometimes, when you are flying around in your elytra while you are trying to navigate through the skies. Whilst a location indicator on the nav UI would make it easier for you to orient yourself with the lodestone location/marker and get to places you have marked on the map with said lodestones. I know compasses exist, but this would make it way simpler to navigate around your world. 

 You could also hoist banners on the lodestone to make custom symbols that pop up on the UI bar as small banner in order to have a distinction between these symbols and what not
