Hi Igor2,
 
Honestly I prefer to do everything from Makefiles. I want to use
sch-rnd and I have installed it but I haven't actually built a project
using it yet (I will later). Thanks for adding it to the list all the
same.
 
I am sure project files work for some, As a feature multi file
selection feels like a thing modern UI's should do here. I know it
won't work for other forms of import.
 
Thanks,
Evan
