Plugin Blocks Category

You can close all categories with

const pn = editor.Panels;
const bm = editor.Blocks

const openBl = pn.getButton('views', 'open-blocks');
editor.on('load', () => { 
    openBl && openBl.set('active', 1);
    bm.getCategories().forEach(c => c.set('open', 0));
});

Or you can use a filter

editor.on('load', () => { 
    openBl && openBl.set('active', 1);
    bm.getCategories().filter(c => ['Cat1', 'Cat2',...].includes(c.get('id'))).forEach(c => c.set('open', 0));
});

Thanks, you can see results here.

I ask here to not open more Bugs:

• is there a way to style the "View Code" button the one with the </> icon?.
• in the "View Code" pop-up, is there a way to hide the CSS text editor only leaving the HTML editor?.
• Why the UI/Style is different on my grapes Vs the official Demo ?.
