Hey DE; Could we get a system where every frame equips a different focus?

Been meaning to make this post for a while and u/Hubframe reminded me. Is there any chance the focus ability could be assigned per frame rather than globally changed?

It's so frustrating starting a mission after changing from Valkyr to Mesa only to realise you still have Naramon as your focus despite not even having a melee weapon equipped, because you forgot to change focus when you changed frame.

While we're on the subject...any chance of making weapon colour and mods save per Warframe as well? It's such a pain in the arse having to remod and recolour a weapon that you want to use on two different frames. I can't think of any situation where the colour saving per weapon would be a useful feature.
