Consider moving entries in search view into overflow by default

Default state:

To reduce complexity, I think we should hide the less important items into an overflow. For example this:

Makes sense. It sort of messes with muscle memory, though. I wonder if there's a way that we can customize what goes there, sort of like the icons near the markdown preview icon. 🤔

@daviddossett ideas?

I wouldn't want to remove them outright, I'm suggesting just like in the terminal view that there are some hidden entries by default:

Some of these were popular requests (clear/run) that I refused to show by default due to the noise, some were added to increase discoverability (scroll). So a user that wants them can right click to add them back, but the default user who probably doesn't want to use them or very rarely does, will get a simpler UI.

This is done via the isHiddenByDefault flag I added:

I'd be happy to have fewer icons there by default too. Clear Search Results and Collapse All feel like must-haves. The others not so much but that could just be my usage.

We could explore this. Maybe hiding the tree/list toggle and also the refresh.
