I like labeling things and having them in their place.
But when a new item(s) has to be taken care of...
If you allow for expansion...too much and you waste space...too little and you don't have the space.
Robert's tube idea might work for me. Particularly if I make the tubes move-able, arrange-able, etc.
Gotta keep the labels visible though.
As usual...the best answer comes down to affording a minion who provides you exactly what you want when you want it.
I'll never find a satisfactory minion.
