Hmm.. I just noticed the new node palette editor and thought of something from another program.. It would be nice to have a similar system of that of houdini. There you press TAB in the node window and it pops you a similar node palette but the difference is that it has a search function. You type the first letters of the node and it finds it for you, instead of browsing for stuff manually. Basically all you use is: TAB, type couple of letters, and press enter and it gives you the node.
