I have my faction colors sorted into bags, a shoe box for pieces that could be good for building, a drawer for Bionix, a drawer with still unsorted Legos and a bag with larger less used pieces and baseplates
My brute "Having enough Dakka is an illusion created by those too weak to stomach true warfare." "A river of blood begins with a single drop."
I mostly sort bricks by colour, but I've also got trays that contain the bricks I use for space ironclads, river gunboats, wheeled vehicles & etc.
Somethings like tiles, baseplates, cones and grates I sort separately and just now I've started sorting anything hinged in a category of its own.
