[Question]: Is it possible to customize the editor completely?

Hi @lorrandavid

It's definitely possible to custom the theme of GrapesJS - you just need to write some the appropriate CSS to fit you needs. Here's a quick, hacky jsfiddle that demonstrates a couple of the items you mentioned: https://jsfiddle.net/ntg9cspa/1/

Version 0.14.5 should work fine with the newsletter plugin. In fact, the newsletter demo appears to be using the latest version at this time.

@ryandeba I'm getting an error for TypeError: t.Panels.getButton(...) is null on line grapesjs-preset-newsletter:15:54147 which is:

t.on('load', function () {
      t.Panels.getButton('options', 'export-template').set('attributes', {
        title: a.expTplBtnTitle
      })
...

How can I solve it? I don't have any 'options' panel

Currently I solved it like this:

editor.on('load', function() {
    var panelManager = editor.Panels;
    editor.Panels.render([
        panelManager.removePanel('options'),
	panelManager.removePanel('views'),
	panelManager.removePanel('devices-c'),
    ]);
});

But I think it's not ideal, because it first shows the editor with all the panels them they get removed, is there a way to improve it?
