You can create a new sheet by clicking the ‘add group’ button or pressing Ctrl+G. It will appear beside the “Time” sheet. Double click on the name of the sheet to edit it.
Sheets can be moved around by dragging and dropping them, or by right clicking and selecting “Move”. For more on moving items, see Move things around in the model.
Sheets will appear in the Excel model in the same order as in the Openbox screen.
