Hi Roland

I had the same Issue.. I managed to get the Customers Name shown, when one Order is selected:

To do so, go to your main addons directory, then to the following:

point_of_sale/static/src/xml/   directoy

edit then the pos.xml

Search for: "OrderSelectorWidget"

Update the following block:

<t t-if='order === widget.pos.get_order()'>
    <span class="order-button select-order selected" t-att-data-uid="order.uid">
        <span class='order-sequence'>
            <t t-esc='order.sequence_number' />
        </span>
        <t t-esc="moment(order.creation_date).format('hh:mm')"/>
    </span>
</t>
<t t-if='order !== widget.pos.get_order()'>
    <span class="order-button select-order" t-att-data-uid="order.uid">
        <span class='order-sequence'>
            <t t-esc='order.sequence_number' />
        </span>
    </span>
</t>

So your new block is like this:

 
<t t-if='order === widget.pos.get_order()'>
    <span class="order-button select-order selected" t-att-data-uid="order.uid">
        <span class='order-sequence'>
            <t t-esc='order.sequence_number' />
        </span>
<!-- rgn -->
<t t-if="order.get_client()">
        <t t-esc='order.get_client().name' />
</t>
<!-- rgn -->

        <t t-esc="moment(order.creation_date).format('hh:mm')"/>
    </span>
</t>
<t t-if='order !== widget.pos.get_order()'>
    <span class="order-button select-order" t-att-data-uid="order.uid">
        <span class='order-sequence'>
            <t t-esc='order.sequence_number' />
        </span>
<!-- rgn -->
<t t-if="order.get_client()">
        <t t-esc='order.get_client().name' />
</t>
<!-- rgn -->
    </span>
</t>

Restart your Odoo installation (systemctl restart odoo)

Now, you allways see the Customers name, if you have selected one.. if no user is selected, the Tab has only the Number
