Improve schema rendering when multiple schemas

Make it easier to see both schemas when there are more than one.

Do you mean displaying them both at the same time? In order not to break the layout at the smallest accepted desktop size, the min width of the repl display is limited to the width of one open schema table.

With the current layout we would lose support for sub 13" laptops like the MBA if we had support for multiple open tabs.

I agree that it would be beneficial to the user to be able to see more than one tab at once. I would recommend that we take one of the following approaches:

• Refactor just the schema tab layout to allow for "floating" tables that can be dragged around and minimized
• Refactor the entire layout to be more responsive

So right now let's say you have two schema, schema1 and schema2. When you open a level, you see an expanded schema1 and a minimized schema2. Now click on schema2. It expands, and schema1 is minimized. But the expanded schema2 now hides the minimized schema1.

So now it's not clear that schema1 is there at all. See level 9 as an example. Initial:

After opening cities:

The minimized missiles schema is totally hidden. Let me know if that makes sense.
