The possibility of drag and drop text pieces has come up several times, but not specifically within the box. I mean, as in text editors: with mouse i select a piece of text, and drag it to another place; or, holding Ctrl key, copy, instead of move.
This would be useful practically for every fields, not only for big ones, as comment.
Yes. It is often more expedient, when there is another piece of text on the clipboard, what i also want to use now, in this edit box. Plus, anyway, only the mouse is faster, than the mouse+keyboard. I have buttons on my mouse, and try in all applications to use only mouse, when it is possible.
Hmm... about your moving image. Basically i mean, drag and drop within the same one edit box. For example, COMMENT. Simply as in text editors. But yes, as you imagined, between two fields, too.
