We know that a typical week is never a typical week. That's why we came up with the Busy button. This allows you up to very quickly mark yourself as busy for however long you like, whenever you like.
For example, if you want to take an afternoon off and you know you don't want to take any bookings, just add a busy period and relax. The same can easily apply to a two week holiday. It's easy.
You can edit and remove busy periods from the agenda tab.
