I would like to see a folder structure to save files into. This way I can better organize files and they can be named the same thing if they are for different projects.

For example: I would create maps for one client. I would name the files by the date on which they were created and put them in a folder named for the community that the map was for. I would have a folder called Baden and a folder called Brighton. Each of those folders would have all the maps that I created for that community. These maps are updated about every week, so in a folder I would have 03_12_09, 03_24_09 and so on. Right now I have to name the files Baden03_12_09 and Baden03_24_09. 

It is not a big deal to add the extra name to the file, but folders would be nice to have.
