HI, I don't know if there is a Script or a Mod to classify GPS coords but I can share what I do that help me a lot to see only the needed ones on screen.

Here is what I do :
1 - Add the GPS coords of all planets and moons to Jump Driver blocks.
2 - Add GPS to AI blocks.
3 - Add GPS to Remote control block.

4 - Use LCDs/Text panel blocks to classify my GPS coords, Uranium asteroids around Earth Moon for example :

This way I can delete the above GPS coords from the GPS Tab and keep only the needed ones to show.

Thanks Dan, but my problem is that there are lots of NPC signals on the HUD:

I mostly want to hide NPC signals temporarily (all or by some criteria) while keeping the gps markers on the HUD.

The "H" key may be a good workaround to hide!?

-> It contains 3 different show/hide signal options and we can see options details in center of the screen when we hit the "H" key 3 times.

o.o ... looks to me like the problem is having too many mods already :P

Point is to hide some type(s) of signals, not all of them:
