Is it possible to customize the side-bar so that the folders do not open like a tree and instead it opens like the way packages are shown in Java IDEs like Eclipse? The package hierarchy is long and the side-bar looks awful with so many sub-directories.
Here are screenshots of the Eclipse Project Explorer and Eclipse Package Explorer. The Eclipse Package Explorer seems to take empty subdirectories and combine them into one name. SublimeText could do similar such as org/emptysubdir1/emptysubdir2
It would also be nice to see class names and method names in the Sidebar.
