User guide

Changing the Page Size

By default, the Page Size is set to 500 which means when you click on any folder, a maximum of 500 items will be displayed in the Grid area even though the folder you clicked on may have more than that. You can however, select a different setting for the Page Size. Once selected, that Page Size is remembered across sessions (even if you close Wonder Lister, that setting will be your default for next session).
