When navigating the project tree, it can at times be an inconvenience to expand folder after folder just to get to the main source files. When I say inconvenience, my point is that sometimes a folder will contain a single folder (no files) and that folder will again contain a single folder. This can go on for 4 or 5 levels and is especially true for libraries installed using composer. I propose that when expanding a folder, the IDE auto expands a nested folder when it is the sole content of a parent. Pretty much like how github will skip through empty directories.
