Sometime it could make sense if one can watch the mouse-movents in realtime.
With ajax it could be done in semi-realtime - for slow connections the mouse-movement could also be recorded and transmitted in intervals or after requesting the next page.
With best regards
while I agree this would be nice, the description above is lacking context; how would this be integrated in Piwik? Do you have examples, screenshot, online demo of existing products providing this functionnality?
eg. would you be able to replay a given visitor mouse path, or would you provide aggregates/summary of a given days visitor path? would paths be clustered into "similarity" buckets?
Please provide more info :)
