Allow manual sender address input ('From' header) when composing
This plugin adds a blue button to the compose screen, next to the identities selection dropdown. By clicking it, a textbox will replace the dropdown, allowing you to enter whatever you want as sender value (it must be a valid "From:" header field value, though).
When replying to an e-mail sent to you through an address not in your identities list, plugin will automatically fire and set "From:" header to the address the original e-mail was sent to.

Once plugin is installed, custom sender button will appear at the right hand side of the identity selection list.
If you want to disable the "automatic replacement on reply" feature, rename
