Dash search box should be shared between the lenses

[Kirill Kabardin]

Home lens contains first matches from all lenses. So we can try search whatever we need right here. But if our query doesn't give us result we have to switch to more specific lens. But search box would be cleared in this case and we'll have to type query again.

It would be more logical not to clear search box when we switching to other lens but leave our query.

At least there should be an option for this.
