Well not an undo button for that but I meant in the application itself, if we were to press and hold on a conversation a menu could pop up with options like "mark as unread, mark as read, mark selected as unread, mark all read"

Also, if it is possible to include a feature to prevent the text app from texting any number in the "home" field of the contacts? I accidentally press the wrong number sometimes and the cell phone company has charged for texting landlines. So if the texting application could give an error message and stop this accident from happening lol
