Response from Melinda Lili Ivany of Smartlook
Thanks a lot for your feedback!
You do have the option to filter the videos according to the visitor country and delete those, so they do not appear in your report, see this screenshot: http://prntscr.com/fp4vwl
Regarding the heatmaps, I recommend to generate a new one after you change the layout of your page.
Yes, visitor tagging is only doable through API, which is only accessible in the paid packages. Same applies to custom names for visitors, there is an API available in the paid packages of Smartlook.
If you have more questions, let us know via our live chat service on www.smartlook.com. Have a nice day!
