Startup display only takes a second or so to open. Initially it gives forecast for eight days. Placing the pointer (no click) on any of the days displays data for that day. I would prefer that the popup data display be off to the side of the initial opening display as it blocks one's view a bit. Clicking on one of the initial eight days brings up a bunch of information. The eight day display stays open instead of minimizing, so to view all this extra information it takes a click somewhere. From this 'extra' info, a click will also display the DarkSky maps (very interesting). Another reviewer commented that the icon isn't visible if using a darker border, but I know where it is. I'm still exploring all the features and information and so far pleased with this nifty addition.
