could be a bug, or it could be by design. Not sure which.
in the 'Productivity guide' there is a feature that is called 'speed search in trees'.
If i am in the 'Project' tree and a sub-directory is open with a file called 'index.php' in that sub-directory and i start typing I-N-D the index.php file will be located and opened.
The bug/issue is when the main directory tree is compressed and i start typing I-N-D the "search for: ind" will be in red indicating that there is no corresponding file.
If this is intended functionality then i am required to open all the directories before starting the speed search. that doesnt seam right. If this is intended then perhaps it would be good to have a button that opened all the directories so that speed search could work.
