In prototypes, comments do not scroll whenever you scroll the page.

This can be fixed by getting the mouse-wheel scroll and moving the comments for each step either up/down (/left/right on horizontal scroller).

This would at least give the illusion of “sticky” comments which many people need.

The most robust approach would be to save the location of a comment in scroll-able boxes by index/coordinates.

This feature is a MUST to be able to communicate with clients efficiently on larger projects.
