Howdy! a couple of feature requests.
1: Breakpoints. I know we can edit them, but they could do with a refresh to cater for todays range of screen sizes. It would be awesome too if we could check screen height as well as width. I have had issues with sites look great on some phones, not so good on other, and I cant control them.
2: Google page speed. Some of the issues flagged by google page speed have come with recent updates to google page speed insights. Some of the issues could be address in the core theme. For example, the header/nav bar image, should have the possibility to be able to add " fetchpriority=high should be applied"
