Using

The application consists of three panels for showing the lists, categories for the selected list and items (either all items or for a selected category).

Each list, category and item has a name. Additionally an item can be in a marked (or selected) state. Some operations operate on marked items only, such as removing all marked items from the current category, or copying all marked items to another category.

The item list can be filtered to show only marked or un-marked items.

To change the name of a list or a category, select the icon at the side of the name with a circled letter 'i'.

To change the name of an item, long-press the item to bring up an option to either edit the item or copy the item to another category. Alternatively, select the Edit option to display the circled letter 'i' and edit in the same way as list and category names. Select the Done option to exit the editing mode.

List, categories and items can be deleted by swiping left on the item. A short swipe requires confirmation by pressing the Delete option that is displayed to the right of the name. A long left swipe immediately deletes the category or item.

When the item belongs to a selected category, the item is not deleted but removed from the selected category instead. The confirmation shows Remove instead of Delete.

When deleting a list, the entire list is deleted, including all its categories and items. Consequently and extra confirmation is required before the list is deleted.

Lists can be backed up by exporting them as a file.
