I am not an designer but wouldn't it be better to make Asset Panel the same colour as bg and just make a vertical line between dashboard and the panel to mark those are different zones. Right now it has a 3rd colour which doesn't occur anywhere else in dashboard. @MrFlashAccount wdyt?

1. With new Asset Panel color the Versions and Sessions buttons are invisible... the same when you want to update description.
2. When you open panel it slides from the left nicely from the right.. When you close the content disappear and you see the blank panel slowly fading. How hard would it be to implement sliding to the right with content in it (so it looks like true side panel)?

@PabloBuchu This panel needs a stronger shadow to match the current design, making it the same color isn't necessary

Searchbar/User "cloud" should have #fff bg

Searchbar/User "cloud" should have #fff bg

not sure about this. i think it would be more consistent to switch to an outline to match with the assets table search bar. @MrFlashAccount thoughts?
