1. It seems Kicad needs all the projects to be in the kicad folder. I
tried creating a folder outside kicad for projects, but kicad then
cant find libraries etc, in spite of saving the settings, and I have
to again add the libraries each time I start. Cant Kicad 'remember'the
settings from the previous session?
I have been saving my projects in different folders just fine. If you
have project specific libraries, after including a library, save the
config in the project folder (default). then next time you open the
project it is there. if you want to always include libraries save the
config in templates\kicad.pro. I just now tried this and it seems to
work fine.
3. I edited the 'DIODE' symbol in device.lib and saved in a new
library device2.lib, did save to memory-save to disc etc. But in
schematic, even after specifically selecting the device2.lib &
selecting the modified component, Kicad insists in placing the
component from the device.lib. How to solve this?
You can avoid this by using the 'Ins' button instead of 'add' when
including your library. put your modified library in the list before
the original library. I still had to restart eeschema to get my new
part. I believe this is the correct way to choose parts because it
allows the user to just type 'diode' and get a diode quickly. but, it
might be nice to be able to change the used lib when part names confict.
