I think the event views (console.particle.io/events and console.particle.io/devices/:deviceID) would benefit from the ability to hide the detail view (right of the events list) when there is no event currently selected).
In devices view having the LAST VITALS and FIRMWARE “collapsable” (as compound block) would allow for the FUNCTIONS and VARIABLES blocks to be accessed a bit easier when doing some tests while also watching the most recent events streaming in.
And having the Publish an event 
button in the devices view too wouldn’t hurt either
