What's the best way to add multiple frames on one screen? Is that possible? For example, how one adds a header except I want to add a sidebar that has functionality within it to every page.
you just...do it? haha I'm not sure what you mean. Frames work just like regular layers in Sketch. Just create them and place them where you want!
hm, like a fixed header and sidebar? it's probably best to maybe create/design them separately and place them on the very top through code
