Sorry to intervene...
Kostya, - I don't know if you've seen my suggestion in another thread. So, just in case, I 'd repeat it here, while clarifying some details about it:
If one can "disable Drafts synchronization while on mobile networks", this would
(1) help with one of the issues debated, and
(2) help to save the traffic in other situations.
In many, if not most cases, if you have a draft of the message stored on the phone, you don't need to sync it automatically while you are writing it.
Writing of a message on a phone while you are on the road can sometimes take some time (if you are interrupted on the road). Even if (and when) it is important for you to monitor the incoming messages (and thus have the auto-sync enabled) - you don't really need to waste the traffic to sync each and every small step of your writing process.
But yes, you may need to sync it at the end of the writing process (e.g. to finish it from the laptop by adding some attachments available only there). So if I understand the sync configuration correctly, if I were to disable sync on the Drafts folder completely (as so far that's the only way to disable that on the mobile network), I wouldn't be able to sync it manually.
You already have separate settings that are essentially "do not preload attachments on mobile networks" (for the incoming messages). I believe my suggestion follows the same logic.
PS. As for the heart issue of Paris Geek's discussion with you, - I haven't used iPhone's Mail app before, so, I had no clue what it was until earlier today I saw the snapshots in another thread.
But my first reaction when I installed -pre6 was very similar to P.G.'s: I didn't understand why I wasn't offered the option to choose the size while attaching the image. And I knew that it was possible to do "live", not only in the "default settings". So, I was confused, - where do I find that... (And I am not the most stupid user.) Fortunately, right about that time I read about the existence of a separate menu item in this forum.
If this is not convincing enough, - here is a different use case:
Somebody who doesn't know Aquamail allows attached image resizing, installs Aquamail and goes with the minimum configuration (because the defaults are very reasonable), - or just blindly updates already-configured app via Google Play store.
He/she may never know about the fact that the attached image can be resized.
(I believe someone here has already brought up this point earlier.)
In summary, - the menu for the "live resizing" is not intuitive. It's nice that that option exists, so that if you changed your mind, you don't need to re-attach the image again. But having that option in the menu while choosing the image for the attachment would be more intuitive. (And you'd probably want to keep it in the menu as well, - for the subsequent changing.)
