I’ve been using the new battle.net app for about 3 days. Looks really good!
I especially like how the central panel (news area) scales when I re-size the window.
Some bugs:
Every time I start the app the tutorial pops up, i.e. it doesn’t remember that I’ve seen this before.
It doesn’t remember which monitor I last used and closed the app on, so it opens on my main screen and is then too large, i.e. , doesn’t open on my larger monitor where it was last used.
It doesn’t fit on my laptop screen - too big, not scaling to screen.
