My friend just meant he wants a uniform Drag and Drop on all Linux Distributions.

Also in the terminal...

Well, it's not that hard. Xlib and Wayland have python(or other higher glue) apis iirc, so you can write it quickly enough. If you know how does each of them work. Mostly a library you use for graphics already has such an option implemented, so you probably wouldn't even need to touch xlib or wayland.

Terminal though would mean writing a window wrapper for bash similar to, well, "Terminal" application. From scratch. And hope it wouldn't be buggy. Just nope.

I feel sorry for tty... (and some anti graphical environment of mine..)
