Opera Mail is NOT DEAD I use it in windows , this is The Best client for mail ! Its great shame that there is no on Linux and Ubuntu, instead I must use the thunderbird.
Second thing what happens bad was removing notepad from new opera and there is no possibility directly add the note from opera to forms and etc.
To his defense there are the previews on hover, the lack of favicon and title in practice serve the purpose too.
But if you want to reload it I assume you want to use it... So why don't you switch to it?
I would reload first while I do other stuff on other tab.
I know speed dial sync is already being worked on (you can enable it with the "Bookmarks backend for Speed Dial" flag. be warned its an experimental flag and could potentially cause data loss), not sure about the rest but I'd imagine at least some of those are being worked on as well.
