I can't even do plated thru holes. What we need that I didn't find, is a pad menu that isn't tied to a specific part, but simply a list of pads we can lay down, listed by ID-OD style in the name of the pad. Dimensions in mils preferred. Having a "pad-039-090" to put on the end of a trace where a wire to the outside world is to be soldered in, and that is easily found in the menu, would be a real advantage to folks like us. Ditto for parts placement, the available footprints I found weren't the correct spacing, nor the correct lead hole sizes. Had that stuff been easily found as single pads to be laid & snapped to the grid, I could have done that 6 part project in half the pcb real estate it took. My experience at laying out pcb's goes back to the 60's at a tv station where we made a huge percentage of our own gear, so working with tape at 4x scale comes naturally to me. We also had a DEA etcher that made 5 minutes work out of making the board once it had been exposed and developed. So PCB to me is a new trick for a very old dog. I made it work, but there were some surprises along the way. The ability to edit all properties of a laid down and re-selected pad (or via) may have been there, but the "how" was not obvious. Not helped by the fact that the help menu's first 3 selections were /dev/null operations. I still haven't grokked whats missing on these two systems that cause that failure. Nothing is logged.
