Foreman would take care that there's at most 1 empty blueprint in the players inventory/quickbar/cursor, if it finds more they get destroyed and Foreman remembers the number. When loading a book from Foreman it will only complain about not enough blueprints if it doesn't have enough "virtual&q...

the remaining inconvenience would be that you can't scroll from the last setup blueprint to the first one as quickly? Yep. I know it's not the end of the world, but I am sure every single user who loads a small book (less than 5-10 blueprints) into a book with all slots filled with blanks is going ...

1. Once i addressed 3. that's how it will work.

If I import a blueprint that has round ( ) or curly { } brackets in its name into Foreman, renaming it via Foreman removes these characters. One workaround is to load it to blueprint → rename using vanilla Factorio GUI → delete an old variant from Foreman → import again. Of course I could use other ...
