Less wasted space in top of UI for simple data

[nikolausWest]

Our web-viewer wastes a lot of space in the top of the UI. This is particularly important since we use the web-viewer when running in jupyter notebooks. The issue is particularly pronounced when we only have a single space view.

Potential solutions:

• Redesign the top bar + tab system to be more space efficient (@martenbjork)
  • I believe this requires tackling where to put the "how to use this view" instructions currently under "?"
  • We can probably get away with not even having the tab there when we only have a single space view.
• Make it easy / default (with blueprint) to not draw any of the surrounding window.
  • I'd prefer at least not making this default. Making it easy to dig deeper and change options is a valuable thing and it's good to be consistent with the full-app when possible.

Another observation: "wasted" might not be exactly the right metric here. If we compare matplotlib, plotly, and rerun, rerun actually stacks up pretty well depending on the metric used to evaluate waste:

• Matplotlib could arguably be considered to waste 50% of the of the horizontal space.
• Plotly also has quite large margins, but they are less obvious due to the white background.
• Rerun feels the most claustrophobic of the three, but it's not due to "wasted" space. I think it's actually due to all the space appearing to be filled despite not being in use.

Even if we strip out all the title bars, I suspect we still actually have a problem of showing an overwhelmingly large image with insufficient margins for visual clarity (depending on the circumstances).

I think you're right. I therefore also opened #2289
