I done a bit more work with diffent ways of aranging the filtering in the side path, adding 2 more filtering methods.
Method 4 seems to work best, so this is now the default.

I created a bit of documentation, including a flow chart, to show how the different filtering methods work.
Iv'e included this in OtherDocuments.zip.

Also I added a new option to reduce the amount of information written to the screen.
