Autohotkey Scripts and XnviewMP

[Brother Gabriel-Marie]

XnView Classic did not use the QT components, so you could use WinSpy++ to fetch the class name of objects in the window.
So I wrote a script in Autohotkey that would:
Change the Sort Mode to Date by sending alt+commands to the menubar
and then scroll to the bottom of the list
Then I attached this script to a command button and put it in XnView's toolbar.

However, I can't do this with MP because MP is just one big class - I can't get a class name for the browser list.
Also, not all the items in the menus have alt-keys associated with them. (the main bar does - like alt+v opens the view menu).

Also, when I point MP's custom command to my script, I have to choose the * filter to get the script. It accepts it, but MP won't run the script because it isn't itself an executable.
With Classic I was able to run any script I wanted just fine.

Here's what I wish for:
1. MP to run a .ahk file or .vb file, etc normally.
2. MP to allow you to send regular MP commands to it (either by commandline or by providing a hidden window where folks like me could setText and in this way control MP from an external program) I can talk more about this if you are interested.
3. allow for the custom command to accept parameters
