The Help File states under "File List":
"By default files in collapsed folders are synchronized just as usual. In some cases you may find it good to change this behaviour to ignore files in closed folders. You can change this setting in View > Options > Settings"
but actually this item is to be found in View > Options > Interface.
Also when one reads the help file, then tries to change to the main program, the help still stays on top. Though this is useful in a few cases, the default behaviour would be better to go to the background, as this is less annoying in general.
