Hi @Louis !
It seems to be great feature the new custom breakpoints.
My biggest probelm with it (not only Cwicly, Bricks it has same problem) that I cant mixing min and/or max values.
Example:
Every breakpoints are great, but I want to add an extra breakpoint for large screen that is more than 1920px (example 4K)
So I want to add itt with @min 1921px and not @max. But every other breakpoint is good with @max values.
