Looking good ghalalb.

The little connectors is a good idea. I've been threatening to use them for years, but have yet to incorporate them into a project.

I think they would be particularly handy on the multiple common ground connections. De-soldering and re-soldering those to the back of a pot can be a PITA (and where I can sometimes let myself get a bit ugly if not mindful).

However, I started doing my common grounds using a ring connector years ago which makes thing tidier. and easier to undo & redo.
