Based on your figure, that's consistent with what I was thinking. The Ellipses look nice on the test label.

Another potential issue is the editable text fields.
It might be good to develop a consistent approach to these editable text fields to prevent the property panel from expanding uncontrollably. My preference would be to grow vertically by the textline height and wrap because that's easier to visually read while editing. Elipses there would make it difficult for larger item names.

It might be a good idea to add a test (probably a test model because it's UI related) with long item names on all text fields so these can be checked in the future with UI changes.

@tompkins-ct Thanks for checking.

Text fields are not a problem: the text "scrolls" out of the text field if it's to long. The text entry widget has no feature to wrap, and I think it's not a good idea to use text area's everywhere.

Thanks @amolenaar!
