World editor problems from a mapmaker;

Hello, Blizzard staff!
I am a map maker. I make content for your game.
Please fix these issues:
1)Described here:[World Editor] Editing or creating a new variable clears the next selected variable
2) Play Music from offset doesn’t work.
3) When you test maps it creates an online game by default. Why? If there’s no internet connection the message appears every time I launch map. I had my internet down yesterday and that drove me crazy.

Also please fix that Night Elves campaign issue - Brothers in Blood - heroes cannot get to level 6 - you can easily fix this by moving all creeps to a separate faction. Please create new faction. All it’s going to take is 5 minutes. And so many people will be happy.
Thank you.

Might be related to authentication/activation/licencing rather than creating an actual online game.
