Long signature validation string causes scrollbars and damages UI

I'd like to leave my humble request for a small improvement that could be done in future versions.

Please refer to the image below to see what I mean:

When the signature on an email is validated, a long string (color green or red) is placed at the bottom of the message showing the success or failure of the signature validation.

Personally, it's been bothering me for a while now that this string is very long and breaks GMail's UI, forcing the browser to show the horizontal scroll bar. Normally, I wouldn't mind having the ads placed away from my view on the far right, but things get complicated when you have an email with long paragraphs. They end up spanning aaaaalll the way to the right and we are forced to scroll along to continue reading it! It certainly becomes annoying after a while.

My suggestion is to get rid of this long validation string and replace it with an icon -- very much similar to the lock icons you now place in the message body, enclosing the deciphered content. This long string could be replaced with a simple icon that shows us if the signature validation succeeded or failed. A detailed message can be displayed as a tool tip (the yellow pop-up that appears when you keep the mouse over the icon for a while).

Anyway, I can't thank you enough for this plugin. I wish I had more time to dwelve into the source code and submit the changes myself for your review!

Great job!
