I recently had an epiphany 
(that´s how it came across to me 
):
it would open up the whole UX and tag system use so much, and offer several cool new/additional affordances if tags could be exposed to the left sidebar, just like lists.
– I know this kind of folder (list)/tag switch from different cool apps. and it always works wonders.
surprised I didn´t make that connection earlier.
but I think lots of my struggle with feeling like going down into the dark cellar/machine room every time I deal w/ tags in GT would evaporate.
– not neccessarily bec it replaces existing possibilities, or bec it would replace a more coherent tag management – but bec it would just open up very easy and above all transparent options to use tags as a cross-list tool for additional & more flexible organization…
