I haven't been using Thunderbird for very long in my Mac environment but i got fed up completely with apple mail over many years and wanted something better which i have found with Thunderbird but there is one thing i am not sure if it will do or is available and that is when i receive an email or send an email i would like to be able to somehow date the email for it to remind me to come back to it in the future at some point. I know you can mark emails and tag them but i would like to see just a simple drop down, mark for future action and the date and the system will remind me at that point by bringing the email to the top of the inbox or sending me an email about it. I don't know if this exists in any way or whether i have explained it correctly but i get an awful lot of mail and sometimes i just want to say remind me in an hour day, week month or a specific time to go back and deal with it. Does this exist in some sort of simple way or is this a big issue to include? I have no idea I am simply a user who likes Thunderbird and would like to see it even better.
