Does a good job

It seems like I’m the first to rate this plugin, so it’s 5 stars because it does exactly what it does.
However, here are some tips:
1- The plugin should have positioning options within the post. For example, before the content, or shortcode, to insert anywhere in the content
2- It is incompatible with Elementor and GreenShift, because it invades space and shows the CSS of these two plugins. This needs to be corrected.
3- You could create other Gutenberg blocks, for each step within the content.

That’s it, your plugin is very good and has a lot of future. It’s a lightweight plugin, does exactly what it promises and is very easy for all users. You are to be congratulated.
