The left side of the screen shows a list of your database items in a table like a spreadsheet.

This drop-down list lets you choose what type of item you want to work on:
cf. Type (Item properties) for a description of each type of items.
Instructions:
Important: the type of items currently displayed is also assigned to any new item that you add with Create (database item).
This button on the list header bar lets you configure which item properties are displayed in the database list.
For each property displayed in the list as a column, its value is shown for each item.
All the available properties are in the form of checkboxes which toggles the display of the corresponding column in the list.

Notes:
Filters are available for many columns.
Some columns can be filtered by text (ex: Reference, Name) to display only matching items. The text filters accept single or multiple keywords following these rules:
Example: type frozen CHOCOLATE in the textbox above the column with Name. This will display all the items containing chocolate AND frozen in their name.
Note: Items with same text values but mixed upper and lower case are grouped in the database list. E.g., Lego and LEGO are grouped as the same value.
Some other columns can be filtered by selecting a matching value in drop-down lists.
Selecting the * symbol means all available items will be displayed in the list.
After you select or type values for filtering, the remaining drop-down lists only display items matching that filter combination, so you can narrow down quickly on available items.
By clicking on the header of each column, you can sort the list according to the column content. For example, to order the list by product names, click on Name. To order it by references, click on Reference. Clicking again on a header reverses the order.
You can select one or several items in the list for further processing or to modify its / their properties. (To learn how to see its(their) properties, cf. Item properties.)
