I copy from/to terminal with middle mouse button. Just select some text and click middle button where you want to paste the text. Some people don't like it because it needs a mouse, they prefer to keep their hands on the keyboard, but I don't see any issues with it.
This way to copy/paste uses it's own Xorg buffer, so you can copy something with Ctrl-C and select something else, and then Ctrl-V will paste the first thing and middle click the second. I have issues using Windows and smartphones because I sometimes try to copy by just selecting things, forgetting to hit Ctrl-C or something. It is really annoying.

I think not. The trouble is programs running in terminal may want to deal with Ctrl-C by themselves. Text editors for example do that, but terminals have no way to know it. Terminals even don't know what program is running now, because job control is a job of a shell.
