Sure thing. The problem we're attempting to address is not necessarily the HTML/CSS/Javascript component of creating a tooltip, but rather the creation of a system and its continued maintenance.

When we hand rolled our own product tour code for a previous project, what we quickly learned was that maintenance was a nightmare. As soon as layouts updated or changed, editing the tooltips we had created already was tedious.

We, however, have plans for other features that we think could really add a lot more value. So if you don't see it now, perhaps later on when we roll them out.
