Vivaldi[0] 4.0 (stable) was released recently. It has 2 major upgrades
that I'm excited about: email and feeds.

I have not had an internet suite[1] since Opera went full Chromium.
I've used mutt and newsbeuter for my email and feed needs... at least
sort of. Feeds are useful and not at the same time. They're good for
reading articles, but is not very interactive (sounds like an Internet
protocol I know). Anyway, the feeds part is very beta and leaks into
my email unreads. Or at least the "unread" part of my Mail tab. Yikes.

Email is also beta. It works for me. Above problem is still annoying.
You can't seem to do much: I can't even make the default open behavior
change the item to read. That's a bummer. But at least it has inline
graphics, which is better than mutt or newsbeuter when browsing items
with images in them.

Another Web 2.0 feature in Vivaldi that I don't like are
notifications. I have them disabled by default, but that only applies
to websites. So I'm met with notifications whenever I open Vivaldi now
unless no feeds or my email has gotten new items. Another "feature" I
could do without. I may end up removing feeds and mail because of
this.

As per usual with Vivaldi, unfortunately there are some broken things
going on. I know it's quite a bit different from Opera's organization,
but it would be nice if the stable branch didn't include so many bugs.
Maybe it's just the Linux port. Two steps forward, one step back.
