Adding an icon to subject column can't be disabled Rated 4 out of 5 stars

Everything works nice but version 0.7.4 now adds an icon to subject column indicating the message was redirected. Probably it is rather useful but not for me.

I used it to send my mail back to POP3 server after I accidentally deleted it (as recommended in Mozillazine KB). All the messages got this icon and I had to manually edit Inbox file to get rid of them (I cleared all X-Mozilla-Keys fields).

It would be nice to have an option to disable marking messages as redirected for current or all operations.

This review is for a previous version of the add-on (0.7.5).
