Borderless and draggable/resizeable unity window? Drag and drop?

I’m working on application based on unity(not game) and i want it to act native on desktop operating systems. I found a way to make it borderless using command prompt(-popupwindow),but resulting windows are not draggable,nor i can resize it. Is there any way(maybe hard) to overcome it?
Also drag and drop is very usefull desktop feature,is there any way with unity to implament it?

Yes, you will just have to create a simple launcher application in any language of your choice and launch yoir unity made it with the specified command line options. There must be a command line option for this too, but you will find it in other sites like stackoverflow.com.
