A possibility to group / order features in assemblies and maybe in parts into functional groups.
Often large welding assemblies have a large number of machining features. Not always these are nicely grouped together for each functional bit. Figuring out which features belong to what function in a tree is time consuming, especially if you have a large part with some small intricate machining, the preview doesn't always show enough detail.
machining lug, rather disorganized
Machining main boss, nicely tight group
A function to create a kind of folder for organizing features would be helpful. Like the folder option for components.
Putting each of these in a folder which designates them would simplify navigating the machining considerably.
