  * Streamline instruction operand editor: don't open a separate dialog
    to edit a line label.  Maybe just show the operand target line and
    invite them to update the label in place?
+ * Add a feature to quickly format "LDA #<lo / LDA #<hi" situations.
+   See https://github.com/fadden/6502bench/issues/120 (related: #21)
  * Improve the "find" feature.  Case-sensitivity, regex, incremental
    searching, "you have wrapped" dialog disable.  Normalize string
    delimiters so searching for "'A'" finds 'A', "A", ‘A’, etc.
