Really enjoy creating custom layouts with flexible fields – one thing that would make it more amazing would be the ability to group flexible field layouts – for example, if you had a ‘header’ group and applied some layouts to that group – when you go to select a layout you would first get the groups which would then exapand on click to reveal the layouts.
I find that some projects can have a lot of layouts and it’s a bit much and can be confusing when they all appear in one list. Grouping them would be an awesome way of keeping everything tidy.
