Yes, there are many. I'm a developer at Wingify, an A/B Testing tool and we are using this library I created a few days back. We have something called heatmaps - https://vwo.com/features/#heatmaps-clickmaps https://vwo.com/features/#heatmaps-clickmaps To view a heatmap, user has to enter a URL, select date-range(Optional), and select the segmentation(eg. Direct, Referral, Location, Device, etc.)(optional). A new tab is opened up with the specified URL each time on clicking the generate button. So, let's say, you have to view heatmap of your site for: 1.The last week and only for those who live in US 2. The last week and only for those who uses Windows 3. The last month and who came directly to your site 4. The entire duration of the campaign and for all users Now, for each configuration, there's an opened tab with the specified URL opened in it and the data for the requested segments and dates. To pass on the data to and fro from one tab to another, and to track the status of all tabs(active/close), to notify other tabs when one gets closed, to notify all the children tabs when the opener tab gets closed, to send a message to a specific tab(eg. change segment) and to send a message to all tabs(eg. fetch data for new date applied), this library comes in handy. All this can be achieved with its simple API. Hope you get the gist now.
