Sugesstion:
Could you add partial names?
A filter on the last level before it gets displayed
Example
We have Fruited Oak Tree(Lumber)(Fruits)
At the moment I have to input "Fruited Oak Tree"
what I want and this is very useful to only input something like "Fruited"
and everything with with the part "Fruited" in this name will be highlighted or ignored.
Would pay additional 5$ for that feature
(Or give me the source and I do it myself :P)
