You can find the tabs on the upper-right part of each group and they allow you to organise more easily your data.
To create a new tab, press on the + button. A pop-up window will appear, in which you’ll be able to define its title and other settings.
If you press on it with the right mouse button (long press in the app version), you’ll be able to edit its settings and its title.
NOTE: We recommend creating a tab per term and hide them when each term comes to an end.
