Add "select all" functionality to the ComboBoxes

I used a different custom ComboBox control in one of my projects that has this capability:
Ext.ux.CheckCombo

It's distributed with LabKey:

./server/internal/webapp/ux/CheckCombo/CheckCombo.js

You can add it to your view.xml file like this:

    <dependency path="ux/CheckCombo/CheckCombo.js"/>
    <dependency path="ux/CheckCombo/CheckCombo.css"/>

Add this is the config parameter that turns on the 'All' checkbox:

addAllSelector : true,

It would go in the File selection comboBox for OpenCytoVisualization.

Could I see what it looks like? I would try to avoid an extra item in the list in the first position that selects all, because I think I have tried that and it is not cleanly implemented (this 'select all' first item is not treated as a separate special item) - I was thinking another button along the lines of the 'clear' and the 'pull-down' buttons...
