Inserts the icon but has problems

The icon picker is really easy to use, just type the name of the icon and pick it from the list. However:
1. If you have along page and are inserting past the fold, clicking the “insert icon” button scrolls you back to the top of the page, so you lose your position and have to scroll back down.
2. The shortcode is used by default, so if you have to disable the plugin you mess up your page, and I can’t see a way to change it in the settings despite what the documentation says.
3. It would be better if you could specify options before inserting the icon.
