At the moment if we want to edit rows in the datagrid this is only possible with an extra pop-up window per line. This is very bad UX in the majority of our used cases. In the webclient it's possible to edit inline, so it would be nice to get that possibility in the client as well.
The most common use case we have over and over is a list of material where we just want to change the quantity. With the pop-up per line this becomes very inefficient.
