Show raw event to sign

[gzuuus]

Hi, I've been trying out the keys.band extension lately and I like it a lot, good job!
I would just like to suggest an improvement. When there is a request to sign an event it would be nice if you could review the event you are going to sign, for example put it inside a dropdown, so it doesn't take too much space in the ui and the user can check if he wants the event he is about to sign. The nos2x extension, and alby do it this way.
