Roadmap

1. Lazily loaded hovercard : load layout without content (with loader in place of content)
2. handle touch devices somehow (at least to disable properly hovercards triggered on hover)
3. Provide context while rendering about where hovercard is being displayed (controller/action/path?)
4. Production / Development diffs (skip loading of validation and debug code)
5. Detached/floating hovercard
6. Document known caveats (small width elements with hovercards have mis-centered arrow)
7. When hovercard is triggered on click: option prevent closing on click outside; sort of “permanent” option
8. Dataset based hovercard, without the need of coup-doeil element (less practical)
9. Events when hovercard open or close
10. A word about testing
