Hello,
why the label of the GND symbol is so far away? I’ve seen many screenshots, where the label is not that far away. Also e.g. the distance of GNDA label is less.
Is there a globel setting for that, or do i have to change every power-symbol if i don’t like this distance?
This is in KiCad 8.x, as well KiCad 9.0

i don’t think there is
if you have autoplacement of labels active i don’t think that you can do much even changing the library.
yes, probably some obsessed people (like me) that changed the position by hand I usually do that an then ctrl-c ctrl-v when i need others.
I never understood the reason to include a textual label by a ground symbol in the first place; it just clutters up the schematic. So I delete it and then ctrl-c ctrl-v to populate the rest of the schematic.
Looks rather far though. Tried pressing “o”?
heres what it looks for me usually
if you use just one GND net, i agree with you.
Sometimes in my boards i have different GND nets/zones, AGND, ISOGND, PGND, CGND and so on, so a way to recognize the net is mandatory.
