Revert left side menu back

Is it possible to revert the left sidebar view back to before the recent update? This new style requires more effort to navigate between the Leads and Customers sections. For example, now it requires multiple clicks to navigate from customer record view to lead list view, instead of just having it right there visible on the page ready to be clicked. I don't see how the condensed version with a dropdown feature makes this navigation section better. It's not like it was cluttered and needed to be cleaned up to begin with. At the very least, can you make this an option in the settings for users to revert back to the previous version, similar to how a user can switch between "Tab View Layout" and "Panel View Layout" when viewing customer records. This would be greatly appreciated.
