ObjectDock 2 doesn't allow for dropping files onto launchers to launch the app with the file as input. This was removed to avoid confusion between launching with the file and adding the file to the dock.
Well, that's irritating.
I just upgraded to V2 and to my surprise found that such basic functionality removed.
It works by default in the OS, objectDock is suppose to enhance my launching/operating options, not cripple them.
To me dragging a file on an Icon to open it with this program is as intuitive as using a knife to spread jam.
ObjectDock that is at the heart of my file organization, please allow this behavior or at least the user choose it as an option!
I guess I will have to go back to 1.9.
