Changing the boostrap collapsing bar width limit


Just wanted to say that with all the new improvements, especially the one that hides PHP and other scripting languages automatically and the easy css access and custom codification, the software is fantastic!

I am struggling with 2 things,

1)I cannot work out still how to copy my header and footer automatically on multiple future pages, I tried to look at some videos but the quality of the tutorials were not good enough on Youtube.

2)This is a big problem for me at the moment, how to change the collapsing time of the bootstrap navbar please? When you add more menus, the bar and logo on the left size hit each others and jump onto 2 lines. I would like to shrink the collapsing bar earlier in Pinegrow, any idea how to do this please? I cannot find a setting for it.
