How to reorder BlockManager Blocks?

Don't remove them, just update and render

const bm = editor.BlockManager;
const colmBlock = bm.get('column3').set({
	label: 'Clm label'
})
bm.render([
	colmBlock,
	//...
]);

@artf It would not be ideal to add an order option like this for blocks and panels.

 bm.add('section-hero', {
        label: 'Hero section',
         order:1, // 1,2,3,4...
        category: 'Sections',
        content: '<header class="header-banner"> <div class="container-width">' +
            '<div class="logo-container"><div class="logo">GrapesJS</div></div>' +
            '<nav class="navbar">' +
            '<div class="menu-item">BUILDER</div><div class="menu-item">TEMPLATE</div><div class="menu-item">WEB</div>' +
            '</nav><div class="clearfix"></div>' +
            '<div class="lead-title">Build your templates without coding</div>' +
            '<div class="lead-btn">Try it now</div></div></header>',
        attributes: { class: 'gjs-fonts gjs-f-hero' }
    });

@JulyanoF you can re-render them in this way

const bm = editor.BlockManager;
bm.render([
	bm.get('column3'), 
	bm.get('column2'), 
	bm.get('column1')
]);

or, if it's just about reordering inside their categories, you can rely on order css property as its container is flex
