My designs are large and particularly power fills are slow. When I add a
via and rename it to one of the power nets, the polygon fill gets
triggered. It doesn't do a ratsnest, but rather rearrange airwires for
the net over again. Even the pads and vias enclosed in the new fill gets
airwires.
Even if I can cancel the fill using the stop button, fills has been
partly executed, and what pops up is incomplete fills that hasn't been
cut out yet.
To avoid the issue I try to copy a gnd via instead of adding a new
followed by rename, but I'd rather see this not happening in the future.
For the same slow fill reason, I'd like to, somehow, be able to manualy
trigger the fill of single polygon, like it has been suggested before.
