Edit default warning text in widgets

I would like to customize widget warnings, for example: the assignment widget says "Your answer is not shown to other participants." For my purpose, using it for a running conversation with admin, it would even be better if it said "entry" instead of "answer." The ability to modify warning text for each widget would be helpful.

The assignment widgets a good example.  Because widgets can be used for different purposes (often different than their intended purpose), it would help to be able to change automatically appearing language to match your needs.   I could imagine a "language" section at the bottom of the widget edit window.
