When an email that is part of a thread is selected the delete button changes places with archive so I end up with a bunch of archives I don't want because I get a lot of mail and delete is my favorite key to spam.

Is there a way of changing this placement behavior or do I need to hack the source and if I do need to go hacking can someone point me in the direction of the file with this evil thing.

Many times, I have a conversation with many messages. I may want to sort the array of conversation fields on any field. Currently, if I click on any field name, the conversation collapses.
