Hello,
"Directory menu" in LXPanel a very useful feature, but it would be even more amazing, to improve functionality, by adding the ability to display not only the directories, but also the shortcuts in dorectorys.
Example: I create a directory "Common" with subdirectorys "Work" and "Home" in it and there's shortcuts to the most used documents.
So, I'm getting a very handy menu with frequently used documents that are available directly from LXPanel on just a few mouse clicks.
