I'm trying to make a schematic and an associated PCB for a specific ESP32 board. I'm trying to make a "library" because I want to put it in several designs (and share with others). I'm new to all of this, but I think I'm doing almost the right thing.  - I have a new "Schematic Lib..." where I've laid out and labeled the pins in a logical manner.  - I have a new "PCB Lib" where I've laid out the pins, and made sure the pin numbers match the ones in the schematic (I hope).  - I have a dummy design where I can place the part, and "update" it with the PCB Lib when I generate a PCB for the dummy design. Two things I'm missing: 1) How can I draw the shape of the board, and some defining features in the "PCB Lib" editor? It doesn't seem to have even a rectangle tool to draw. I'd like to make something for the silkscreen to help orient the part when it's placed on the final boards. It would also be good to have some kind of visual of the size of the part, so that you don't put other parts too close (Is there a layer that doesn't end up on the boards? 2) How can I connect these two things? Is there a way to connect them permanently so that people can easily use them together?
