Convert the initial new scenario button to a collapsible drawer where it's possible to view and open available scenarios.
Based on these Figma mockups.
Description
The change to a drawer has implications for the possible tab interactions.
A new tab will show on the list iff it has been committed (its world is created)
We need to limit the number of right tabs that exit to avoid overlapping issues with the drawer.
In the drawer, should we show an indication that a tab is already open?
Should it be possible to delete scenarios from the drawer (permanently delete scenario)
