I realize you can jigger the "open with" to do a similar thing by making a script one of the open with items, but it is very hard to control where it appears in the menu and Viewnior adds stuff to that menu making it unwieldy. It would be a lot nicer if the native menu were editable, perhaps with a config file kind of like 9menu menu files. Failing that, almost as good would be one entry in the top level of the menu that pointed to a standard path/filename that would call any script there the same way "open with" does, with the path/filename of the image file as an argument. Then we could put anything in the script, including another menu for example. 3rd choice would be for just the "open with" submenu to have the option to manually specify what's on it instead of having it change automatically.
