I shared these ideas in previously on this post  but sharing here again so we can have a healthy discussion on these features.
These are the Ideas

    I want to propose a UX related adjustment. Joplin provides three type of layouts… . 
1. Full screen writing
2. Full screen viewing
3. Split screen (write and view in parallel)
Speaking of my self, I don't like Split screen writing. So every time when I want to switch from full screen writing to viewing or vise versa, I have to click twice which is very uncomfortable.  And I believe it would same for someone who prefer Split screen view. 
It would be great if you provide three buttons, one for each layout instead of one. I am attaching a quick drawing that will help you to understand my point.

Focus Mode 
  
  
    These designs looks awesome. But not really a fan of moving the text formatting toolbar anywhere else. It’s the best place for it to be IMO. Maybe a zen-mode that hides all sidebars and toolbars? Now that’s what I’d wish for.
   
 
  
  
    Nice design, very clean and simple. Any chance of it having just the Note editor maximized with everything hidden so that you can stay focused on writing… like iA Writer?

Feature we can implement right now in Joplin 
Fullscreen Icon - In the toolbar we can add this button 
Layout Icon - This will let user know the current screen he is using. Just need to change the icon of layout in toolbar 
Hide & Show for Joplin 
 
Focus mode is not complicated, it will just hide the sidebars and will play with opacity of objects, like this
Properties - Instead of showing Note Properties and content properties with different icon, we can show them using single icon 
 
I like to know everyones opinions on these Ideas

              Can anybody take a look at last three images?
             
            
              
                
            
           
          
            
            
              This looks very good; I hope it will be implemented. For me, I particularly am looking for the full screen (distraction-free) mode.

              Distraction free (focus) mode and full screen mode would be great, also presentation mode with a bigger font and spoilers (sensitive information) not showing for the audience
             
            
              
            
           
          
            
            
              Hi,
I'm new to Joplin, I often use it on a vertical screen where there isn't much room in width. So I use the keyboard shortcuts to toggle the sidebar and the list of notes, and I also often have to toggle the panels of the plugins I use: Favorites, History, Outline.
A button to toggle everything at once would be great.
While waiting for the possible addition of this functionality, are there other solutions?
I saw this but I don't really understand what to do, and I'm afraid it might be risky:
  
  
    Re: One button to toggle on and off the sidebar, notes list and favorites 
Hi all. In case anyone is interested, I managed to work out how to fix this. The current visibility of panels is held in a global setting, so I use that. I can't just use the existing toggle commands, because the order in which you make each panel visible and invisible is important, and different depending on whether you are toggling on or off! 
If you happen to want a button which toggles the sidebar, notes list and favo…
   
 
Thanks
