Unity indicatore-datetime is missing features from the classic gnome indicator

Apparently due to Unity nature the applet had to be remade. But on this remake are quite a few features still missing from the old classic date and time indicator, most notably the ability to see the various positions on a map, the auto-ordering of names depending on their timezone, the indication of the local timezone next to the location name, the difference between the current and the local timezones to allow easy calculation of future time... Basically everything that was on the old applet is a missing feature for me. I'm travelling a lot and I'm contacting people from other parts of the globe and the new applet is clearly a regression in features. And the ability to see the local weather was nice too, having a link with the new weather applet for them to share information (locations and weather) would be very nice.
