Does anyone know how to do this? For example I need dreamweaver to open a file (.tpl) but i cant drag it into the dock and it is grayed out in the open dialog. This is just an html file so it seems quite lame that I can't open it. Where are these rules about opening formats kept. I think there should be some modifier key or something that would let me override these rules. Or I would like a setting that would just turn them all off, and let me open what I want with anything I choose.
