FEATURE REQUEST: WORKSPACES

[Funtaztic 0]

Hi Evernote Team and all dear fellow Users!

Let me introduce the latest new Evernote feature:
Workspaces!

In a nutshell:
There would be separate windows/tabs in which we could customise the layout of the Evernote window.

The idea:
When I work on my professional notes, I do not need any other, non-related stuff. Just like online, with the 'focus' mode, I think you called it. 
The main reason behind it is the shortcuts. I would need much more shortcuts to be visible on the top bar to be as effective as possible. I would need some selected group notebooks and tags for each workflow.

I am not a program designer, I have no idea how this would be possible. Still, I had an idea and I wanted to share it.

Please see the attachments to get a better idea.
