Not sure if this is possible somehow or if it would be a new feature, but it might be very useful to be able to see all of a board’s schematic symbols grouped as a library in the symbol editor. Or maybe a set of libraries, one per sheet in the schematic.
The same would be very handy with the board footprints, being able to see them all in the footprint editor under a library named “Board” or something.
This could make it faster to edit symbols and footprints rather than clicking on them in schematic editor and pcb editor and make it faster to import and export between the board and various libraries.
You can do half of what you’re looking for right now by exporting all symbols or footprints to a new library and accepting the option to update library links to the new library. Worth experimenting with using a copy of your project. Try File > Export > Symbols to New Library from the schematic editor (or the equivalent from the PCB editor).
KiCad-cli can export SVG images of symbols and footprints It can either export a single symbol (or footprint) to an SVG image, or it can export all symbols (or footprints) from a library to SVG files. Having an overview of all symbols (or footprints) in a library is useful for library management, but I would rather have them in a schematic (or PCB) file.
I am thinking of making a feature request for KiCad-cli to add the ability to export library items to a schematic (or PCB) file. I think this would be more useful then creating images of them. But I first want to upgrade to V9, and then check gitlab whether some similar request is already present.
