Help: How I can set the default map view

Hi I am making a map with TimeMapper but when you open the map is displayed in the whole world map and I would like to set a default view, also at some points the dates do not match I put into database
Also I wonder if you can change the map icons

Greetings and thanks, hopefully someone can help me to correct this.

I attached the link to the map Mapa - TimeMapper - Make Timelines and TimeMaps fast! - from the Open Knowledge Foundation Labs
