Display info when entering subdirectory

[nelgin]

It'd be nice to have a hidden file (.info for Linux maybe which will be displayed when you enter a directory. You could have some notes about what files are in there, especially if you have a series such as an instructional series CD1, CD2, CD3 etc. You could put .info in CD1 which explains what is in that directory.

Conversely, there are some directories I don't want to show up, like lost+found. I'd like to either put in exceptions in the control panel or maybe create .hidden file in the directory for it now to show.
