Questions. Just installed 2.10

[Lone Wolf]

Ok so I just installed 2.10.06. I don't know which version I was using earlier and it hasn't been for a while, it seems part of the tool box that used to pop up on the right is gone. Still that way with this version. Is there a way to restore?

Also the default colors are now gray. Don't care for this back  ground. Is there a way to change that?

I'm sure there will be many more questions forthcoming.

Thanks
