"Crypt and Send" button scarey?

While it is a possibly useful feature to only sign or encrypt the amount of text one has currently selected, when I tried out the "Sign and Send" button and ended up basically signing null, followed by the rest of the message, unsigned, this makes me wonder if someone could accidentally make the same mistake when encrypting a message, and not have it selected?  If they use the "Crypt and Send" button, is this not very scarey? the message will be sent without any opportunity for the sender to visually verify that the expected behaviour happened.

Does this maybe make the "... and Send" buttons dangerous, especially the "Encrypt and Send" button?

Maybe a way around this could be for FireGPG to check if there is very little selected when an action is effected, such as no text, or maybe just less than one line of text. Then FireGPG could at least, not include "and Send" in the action.
