feat: Usability improvements in the GUI application

* Sorts the table view on the Sequence column (when it is present)
* The table dropdown is a DropDownList
* Columns in the property grid are automatically sized
* Columns in the table grid are automatically sized

Thanks and kudos to @learn-more ! 🎉
