This wish is for the modification on how composites work. At the current moment you either make a composite for each variation in cladding which can clutter the composites list or leave it all generic.
The proposal is for the ability to layer composites so that you can instead have a library of composites which contains just half or a third of a wall structure, which is then layered within the wall tool to create the finished wall.
Do Offset Modifiers not do what you want when using a complex profile? On the theme of zero thickness, OMs will allow zero thickness to make things disappear e.g. zero thickness offsets do not appear in things like skin lists.
I find complex profiles more flexible than composites for modelling walls, it's a shame they don't currently translate to roof, shell & slab type elements.
