TW3.0 loads faster. While in TW3 you can already see the skin in TW4 the loading bar is at 22%. When the first scene starts in TW3 the loading bar in TW4 is at 41% and the first scene opens whilst in TW3 has showed almost 50% of it. Even when opening both tours again, once closed, TW3 loads faster, almost inmediately.
You linked the instructions and info buttons also to play and pause the movie. In some case this is ok, because while reading the instructions or the info about the location, the tour stops. The inconvenience is when both pop-up windows are opened at the same time. The first one pauses the movie and the second one starts it again. I know doing so is not the normal process, but it is something to consider. Maybe it is to detailed. In spanish you say: "buscarle el pelo al huevo".
Nice and sharp imagens for only 230kb. Congratulations.
Thanks for the info about the forecast and counter. Nice!
