Roadmap

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