Since most themes utilize the H1 tag in the template for semantic SEO markup, there’s no reason to allow the h1 to be used in the WordPress Editor. Tis plugin easily removes the H1 tag from the editor within the WordPress admin when activated.

With <a href="https://github.com/pixelgrade/pixcodes" rel="nofollow ugc">PixCodes</a> you can have a shortcode insert interface for the WordPress Classic Editor.
PixCodes is intended for Classic Editor and TinyMCE workflows. It does not add a block editor interface.
The awesome part is that you can filter any shortcode parameters or overwrite any shortcode template with your theme.
Note: this plugin does not add any style to the output of shortcodes.
We believe that shortcodes functionality should be offered by a plugin and the style should be provided by themes.
Here is a <a href="http://github.com/pixelgrade/pixcodes/blob/master/README.md" rel="nofollow ugc">detailed documentation</a> about how you can configure some plugin settings and output.

PixCodes offers a Classic Editor interface for inserting Pixelgrade shortcodes.
