I noticed many people don't understand why HFS saves automatically options but not the file system (vfs).
I also thought over a lot of people who don't need to play with more than 1 file systems.
What i consider doing in next version is
the first time
- you quit with an unsaved vfs
- hfs asks you if you want to see your files next time
- if you say yes, it doesn't ask for a file name, but automatically save the vfs to an hfs.vfs file (or in the registry if you save options to registry)
other times
- if you answered yes, it continues to automatically save vfs at quit without asking
You can always stop this madness by using "save file system".

giving a name to a file is a job many people consider boring.
i think this should improve usability for basic users.
