Ok, firstly I would like to say , I love this mod.

However, I have come across an issue, I am unable to "shift=Mouse wheel" to scroll through blueprints in a book.

Thank you

I am glad to hear that :)

Could you please go to the Settings / Controls, search for "zoom" and show me the screenshot of the key binding you set?

I didn't set any key bindings. All are default. Do I need to change it?

Ok so I set the controls exactly how the picture shows and all works great. Sorry bout that. :)

I am still curious what settings you had because I haven't encountered this problem. I am only guessing that it was some sort of collision between controls - i.e. the same control assigned to do different things, but I cannot reproduce it.

I know that defaults are not great - the mod cannot assign the mouse wheel to quick zoom in/out but this is extra functionality. Base functionality (overriding what zoom in/out and alternative zoom in/out actions do) should work with defaults.

I thought shift scrolling through blueprint books was no longer a thing in 0.17

I had the same problem. I don't know if it is this mod, but in settings - controls was zoom in and out set to mousewheel and shift + mouseweel. After I disabled the shift + mouseweel the scrolling through blueprint books worked again.
I don't know, if your mod changes something about that...
