* There is a circular update loop I had to cut off where the name field
updates the filter and then the currentRowChanged signal is firing without a row.
* I chose to make a private method to show intent instead of relying on
other QLineEdit methods (textEdited) that don't fire signals.
* Some other shenanigans may be at hand that are causing this
workaround, but my familiarity with Qt is pretty low.
