Just WOW!!
Thank you - I'll be looking into this soon.
Before I've managed to have a detailed look - is there a way of telling if the extension is installed or not to know whether a script can use the new available functions? I guess this would need to be a native Reaper function.
I like the look of Window_Resize and Move - does this mean a script can resize it's own GUI window?
EDIT: Oooh - just also notice MOUSE_SetPosition - one I've been wanting for a loooong time
Thank you again! This is going to be massively useful!
