This would be nice to have. Maybe something like Ctrl+Alt+F makes everything go out of view with a smooth motion transition. The funny thing though, you can do this with Minimalist for Everything, a nice extension I found on the Chrome Web Store. It allows you to add CSS/JS to a website so you can get rid of the clutter. Until this idea is implemented, you can do the following:

1. Install Minimalist for Everything (link: https://chrome.google.com/webstore/detail/minimalist-for-everything/bmihblnpomgpjkfddepdpdafhhepdbek)

2. Go to app.thoughtplan.com

3. Go to the little M square on your Chrome bar and click on it. Click Add Module on the little popup that appears.

4. You are now in the dashboard. Go into your new Thought Plan module (if you haven't already), and change the @includes input with *app.thoughtplan*. This will make the applied CSS/JS modify everything within the Thought Plan website.

5. Go into a option (One was probably made for you already with the structure "General - General - New Option), and the following code into your CSS:

.navbar, .bottom-nav, .thought-plan-header { display: none !important }

This will allow you to hide everything. To turn it off so you can see everything again, simply click the power button next to your module with the Minimalist for Everything extension and refresh the page.
