1: Why can't I simply move from composing an email to the many labels without being warned about losing my work? Yahoo figured this out and so should Gmail.
You can and it does. Not sure why this is not working for you. It brings up a pop-up that says: "Your message has not been sent, do you want to discard? OK/Cancel". You can also click "save" at any point to put it in your drafts folder.
2: The interface is still wanting big time. Heck this is 2010!
This is subjective. Much better than any other web interface in my opinion. As others have said, you can use IMAP if you like. Also, the education edition which Yale would get can use an Outlook MAPI plugin (very fast!)
3: Though Gmail's search is fast, filtering is still so basic. YahooMail's filter is good. Google can surely do better. When I search for an email from someone, I would like the opportunity to filter further "on the fly"...in real time...say by attachment type if any, subject and so on. Currently the filter functionality does not cut it!
Again, this is a subjective interface preference. I would prefer it wait until I click "search" again.
4: Sorting by sender, subject, time of arrival etc is non existent! This is on a service that prides itself on users never having to delete email! For those with tens of thousands of email, Gmail is mediocre!
Try the "show search options" link. All the features you mention are included. No need to know complicated codes. I'll grant you that searching by exact hour or minute is more difficult (requires manually structuring your query), but that is a small issue easily solved by education.
144,000 for "i hate t-mobile"
468,000 for "i hate verizon"
444,000 for "i hate at&t"
286,000 for "i hate sprint"
Searching 'I hate t-mobile' on google (no quotes) comes up with results that include "i", "hate", "t", and "mobile" separately. Your research method is highly flawed.
I watch U.S. public television myself, and I like a lot of the programming, but I would still support eliminating it because I don't think it's a good use of public money.
