Rather then having the 992 as the fixed base point it would be great to enable to pick your own base breakpoint. Be it a larger one and then work your way down or start from mobile and work your way up. Now working from the 992 breakpoint and then making the adjustments for the bigger screens, make no sense since the design files are per definition always made for a larger breakpoint. 992px is an outdated screen size, especially for using it as a starting point.
somewhat outdated when it comes to the bigger breakpoints. But however being able to start on mobile and work your way up would still be a good to have for clients that really emphasise on mobile first.
