I added the other features that I wanted including the defaults and reset buttons as well as the update coordinates and scale buttons.
As you pointed out, I fixed the typo you pointed out with astrometry.net versions and  added more tooltips so everything now has one.
I added a working combobox that can do several different units and updated the regular argument generator to also be units-friendly.
I made the interface look prettier.  I handle bad text entries into all of the boxes except the large lineEdit.
And I worked out most of the bugs.
