Especially for plotting layouts, depending on use case, it would be very useful. Often I need to change plot options (for instance depending on if I want to generate Gerbers, or generate DXF files, etc) and the probability of missing some key option (especially going back from DXF to Gerber), due to the amount of options available, is significant.
Saving plot options for the schematic editor could be a plus, but definitely not as critical.
Thanks. I can see a number of good related ideas in the thread you mentioned, and a number of related threads. A bit sad that it doesn’t seem to have been assigned to anyone in 3 years, unless I missed it.
