XnView Software

I would love to see a custom command in XnView for adding own batch script.
Lets say you've created a complex batch operation, and saved it under some *.xbs filename. It would be great to have this script as a button(Options>Interface>Toolbar>Buttons>Append...(command dropdown list)), on XnView toolbar.
Could you implement this, please?

And by the way, i'd like to be able to apply the same batch to the opened file(in a view window) as well.
Lets say, you've opened the file, and want to add those complex transformations you've saved as a script. You just need to go to the browser, and only that way the file name will be on the Ctrl+U list.
It would be nice to have an option to open the file>apply the script>ctrl+s>done

FYI: How to "Batch" several commands via Icon in the Viewer?

Better that nothing, cheers mate. But still, Its not a one button click.
