Opera is still not getting some basic features right and that is costing them users. I remember asking for a feature in forums in days of Opera 11.00. The feature was something that every browser has: "Remembering contents of a text field." For example, when I enter my email address once in a website and then come back another day and write first letter of my email id, it is displayed in a dropdown. But Opera outrigh…
Opera has an inbuilt IMAP client... which I admittedly never use, but between that and Thunderbird, why would you even want to use webmail? Of course it should still work, even though it's silly, but you also "should" not even notice that it doesn't, is what I'm saying. Certainly if you imply your time is so precious, heh. And what is wrong with F11?
I have six email accounts setup in my Opera, all using IMAP. There's a unified INBOX so I can check all my messages, but still be able to review each INBOX separately. Email search is BLAZING fast, the fastest search I have ever used, though it lacks advanced search options like searching only in the subject.
The contacts view is also awesome. Click on a contact and it'll show all the mail to and from that person, instantly. No searching.
The best part is that I never have to "check" my email. Opera notifies me as soon as I get an email (thanks to IMAP) and I keep open the sidebar on the right so I can always see the UNREAD counter to know if I have new messages or not.
Since reading email and browsing the web are things I do all the time, it really makes a lot of sense to me to have those two activities live in the same window and use the same tab navigation system. I love it.
