How to edit a project library?

Clicking the “UDCM QFN3x4…”
I’d expect the footprint editor to open.
Instead, I get nothing but the main/read-only library.

Not very intuitive design, please help me understand the intended way to use it.

Your confusion is understandable.
The view on the left is just a directory tree view, while the “tradional” way is to:

  1. Add your library to the library entry table.
  2. Open the Footprint Editor.
  3. Browse to your footprint in the footprint editor.

Which is a bit convoluted.
KiCad can open .pdf and .txt files from the tree on the left, so I thought I’d make a file association between a footprint file and the footprint editor, but I can’t even figure out the filename of the footprint editor. I thought I’m smart, so I had a look at /usr/bin and sorted by file date. (Apparently I upgraded to KiCad V8.0.6 on 2024-10-15) But neither the footprint, nor the symbol editors are mentioned separately.


My best guess is they are not separated programs, but integrated into the KiCad binary.
