Dear Ideas space,
thank you firstly for providing this opportunity to share my (old, untold) idea, which I like to present in this manner, to actually explain better, which is what I do best. (No judgements, I'm bad at delivery, I get that all the time. I may be understanding my own emails.) Concisely, and somewhat correct;
I'm interested to know 'why you're (all) choosing for HTML'. (Worded a bit like a magician.) That will become apparent. (Because I have an alternative, you're looking at it.)
Also, an email with 5+ MB attachments can go separate ways; mail and upload to the [password access, user specific, per user/group] place of your choice (which it is all about; standard off, like internet addresses standard off for Firefox, separate idea, "just" security patches, but you get the drift), large attachments to a separate address (such as the local machine of the recipient itself, not in the inbox file but a local map). It also 'modifies the email I sent earlier', though you don't have to know that.
(Bare in mind please, these do look like separate ideas probably maybe deserving separate threads, I must not forget to mention, but it will become apparent when these all are part of one idea, actually 'better than HTML emails'. Though it's not an HTML vs plain text discussion, I'm just bad at show and tell.)
Makes the user specific receipt requests (not for everybody) also I bit easier.

Thank you for your indulgence and your patience. I think I've not, and I shouldn't, disrespected the rules for this platform which is connect.mozilla.org. Thank you for all goodies. Thank you and thanks again. This is all about technology and giving back.
