Responsive email template builder using Grapes js

@ateshuseyin @artf - Thanks for the great plugin. We started to use Grapes js in our project as an editor for building responsive email templates. In order to achieve responsive emails , we have two choices.

1. MJML - https://mjml.io/ - working in Major email clients
2. Custom HTML/CSS - https://webdesign.tutsplus.com/tutorials/creating-a-future-proof-responsive-email-without-media-queries--cms-23919 - Working some clients only. But not sure

Our aim is to develop something like this http://react-email-editor-demo.netlify.com/ using Grapes js. I hope we can do. But before that, I came know about MJML language and Grapejs has support for that too. But it has some major problems like,

   1. The repo has no recent activities
   2. You mentioned some comments in the code like 
         "// Currently the UX sucks too much with the heavy rendering  approach" 
         - as you said it takes more time to rerender DOM even for a single style change
   3.  Minified version "grapesjs-mjml.min.js" is high in size ( 1.3 mb )
   4.  MJML parser is a heavy engine and this is also not supporting for browser-level 
     extent in its new version    -   https://github.com/mjmlio/mjml/issues/928 
           (I upgrade to recent MJML4) . But it sucks.

So, need some suggestions from you that,

1. Is it possible to reduce the size?

2. Shall I proceed with this MJML or custruct my own components using Custom HTML/CSS as mentioned in second point? If constructing own means - Need to achieve all the things...as you did in "Grapejs MJML"

3. Can we remove MJML parser - (import 'mjml2html' from 'mjml') and map that generated html code as a custom component. for Example

  MJML format        -   <mjml><mjbody></mjbody></mjml>
Generated HTML   -   <!--[if mso | IE]>.....bla bla bla.......<!--[if mso | IE]><![endif]-->

Here, Can we create a custom component, where the "ComponetView" returns the generated HTML as hard coded. (But it's fairly not possible)

So I'm stuck with this approach and please help on this @artf
