Note the buttons on the right of the window. When the filter in text box becomes long, it extends the text box and pushes the buttons to the right. I think the text box should remain fixed in size and let it deal with the long text, not push the buttons off screen. There is a slider to deal with it, which is good. But it is non-standard behavior.
I’m creating second Work Item view to keep the generic items separate from all the project and support incident work items. They are starting to pile up.
