Combobox in system generated dialog for V2.99.18 Python script
Am I missing the obvious or is it not possible to define a Combobox/option parameter in the gproperties section of the class definition of a V2.99.18 Python script? This means that the script has to generate it's own dialog - not a problem but it doesn't then have the "Load Saved Settings", "Save Settings" and "Reset" buttons that appear when the dialog is created using GimpUi.ProcedureDialog.new(). Having these buttons would be useful and also maintain a common appearance of the dialogs.
I note that the SpyroGimp script has to generate it's own dialog, presumably, at least in part, to be able to show Comboboxes/drop-down widgets.
(I realize that I can define the combobox as an int type in the gproperties section and then create my own dialog but but as noted above it would be good to be able to use the 'standard' approach and to have the extra buttons)
