Improve UI Layout

[skrawcz]

Problem

The current layout leaves a lot of wasted real estate and also means I cannot see the data and the graph at the same time.

Proposed Solution

• move the graph under the sequence list
• have the data pane on the right take the whole side. We can then subdivide the data pane more easily (e.g. to handle large state objects).

More things:

• want top bar to stay like you can do in a spreadsheet, so you can toggle raw/render and stay in place.
• also want how github shows what function you're in when things are collapsed so you know where you are/what you're looking at -- e.g. that could be in the top bar.
• when the left is minimized, you can't see what the name of the action is that you're on.
• render forms components should be collapsable -- could even allow people to specify a config as to what to/not to render.

Most of these are solved by: #121

Closing this initial ticket. We can create more.
