The part std is too advanced for me too, but non std bad parts aren’t great either. Some old parts are so strange in their format and have so much junk attached you just have to throw them away and start again because it’s too confusing to just do a simple mod to make into something else. Standardised parts would make mods much more simple and would be faster than making new. Basically it pain now for reward latter.
You can ‘Trace to Bitmap’ PNGs in INK - I have a tutorial - and just add some connectors. For one-off or low demand parts this is probably the best way.
I was thinking about getting rid of the BB view, or changing svg drawing to CAD drawing so we have 3D view because it’s the same work as now, but basically BB view is the only reason it should exist because there is plenty of other EDAs. Besides helping beginners it’s good a documenting stuff for tutorials.
BB view is complex to draw, but everyone trips up on the group structure of PCB view so it’s probably not as simple as getting rid of BB view.
