The price to pay is that to see individual effects for tuning, you
have to note down all the values you do not want to see, input zero
and when done, set them back to the old values you manually stored.
Using many texture channels could workaround that issue (if the
texture limit stops being so low), but cause having to sync many other
settings. Matt idea solves it.

What about textures for brushes? Or displace modifier? Or being part
of a node tree? Or <fill blank>? Current situation is bad, having to
add materials and disabling them because if totally unlinked from the
material, editability is lost. So solving those cases for once would
be nice.
