Android 5.0 Key Lime Pie: Five features we want

The version of Android 5.0 Key Lime Pie, seems to be presented in mid-May in the event Google I / O. Almost one month would be your staging and barely know anything about the innovations that will bring this operating system evolution.

Therefore, before ignorance and expected to arrive official news-if at all-on developments will bring the new version, we decided to make a list of the five features we wish to include Android 5.0 Key Lime Pie.
We begin with the first three:
1. Widgets on the lock screen and home screen: It was an attempt to incorporate more widgest on the lock screen in Android 4.2, but they were few apps that could be included and some customizable. We would like something that would provide additional convenience. Regarding the home screens, it could use some creativity.
Two. Profiles yield is something many users miss their Android devices. Performance management in current versions is something involves considerable time and effort, so an option that would make a more effective performance management would be useful, for example to take advantage of the full power when you are playing and download to the When minimum consumption decreases.
Three. Better support for multiple devices: Better support cross between devices, between the phone and the tablet for example, plus a live synchronization between the two terminals one to continue where I left off on the other.

The last two features we would like to include Android 5.0 Key Lime Pie

We continue with the features we would like to include Android 5.0 Key Lime Pie. The last two would be:
April. SMS in the cloud to store the SMS in the cloud would be useful for users who use more than one SIM card or multiple users of the same Android device and the SMS synchronization between devices. The ability to access these SMS from any terminal would be very good.
May. Upgrade option: there are times that updates make a device to work worse than before installing the update, so anything that's something that should not be imposed and should be the user himself to decide whether you want to update your terminal or not.
Anyway, do not know if the new version of Android 5.0 Key Lime Pie will include some of these recommendations, but hopefully at least incorporate something similar.
