I'm often not mobile anyway - or not in any way that would involve log ins directly. If I'm mobile I'm pretty much exclusively using the reply by email function, since that way if I'm suddenly called away (which is a not infrequent occurrence) I can just let the email autosave hang on to what I've typed up, rather than hope I don't accidentally close/back out of the tab.

But I have heard of those options, yeah! I know some people who use them, and if things get super frustrating, I'll probably check them out.
