-Id like to see the Node Editor workspace become a little more generalized so that you can show meshes, textures, and modifiers (like displace) all side by side. (Textures do more than texture these days).
-Perhaps The area should be split into several parts. A general scene graph on one tab, special workflow Area on another tab (materials, Textures), and Compositor on another tab.
______________________
*Display everything in the scene Or limit what you want to see using toggles at the bottom of the window.
*Should just be able to right click on your texture node to get options like "Show Output(s)", "Show All Connected" or whatever else might make searching through a scene easier.
*select "Show Output(s)"
*Outputs will be shown and the rest hidden
