Hello, it looks like there is no handy way of isolating pads/tracks from a copper area in the same net. It's advised when using decoupling capacitors etc. I tried to write a plugin to make it easier and it kinda works but only for tracks and standalone pads. I think it would be very hard/impossible to make it work with footprints with the current API.
This is what I got:

A dropdown menu lets you select if the pad/track should be connected to a copper area.
@UserSupport Could you please consider implementing such a feature?
