Add animations to browser

Add animations to browser

I had a bit of a realisation about how we could do open animations for the browser panels. It seems to QA accross browsers and even though the panels don't animate on close I think it's worth having.

I'm hoping this might be enough that we don't have to worry about animations on close...

There is one point which might be considered a bug in that the panels will animate in on page load instead of remaining in the open state. I think this is an OK trade off, but others may feel differently.

LGTM QA OK

I think this is great good work! The animation in on page load looks awesome
(IMHO) and even though it doesn't animate closed one could pretty easily make an
argument that the user wants it gone so closing really fast is a good thing :)
