When entering invoices directly from the incoming invoice list (blue button at the top right), the focus should go directly back to the list view after clicking on “Create...”, not into the details of the invoice, as this is often entered by separate people. You can access the details at any time from the list by clicking on the document number. Clicking on the project label should preferably lead directly to the incoming invoice list of the contract (under external costs, additional costs) or to the incoming invoice list of the respective sub in the contract (under external costs subs), not to the project overview as is currently the case.
