The company Ixonos showed a demo video with its new development - multi-window mode on the tablet running Android. The Nexus 10 with Jelly Bean 4.2 serves as an experimental sample.
As you can be sure, you can perform the same operations on windows as in desktop systems: open, close, move, maximize, minimize, resize (plus global operations, such as “equalize proportionally” or “on the grid”). Subjective feeling - it works really fast (except that the resize is a bit jolted), despite the fact that such heavy applications as Google Earth and YouTube work together, and in parallel with them Angry Birds is launched. About how this is reflected on the battery does not say. ')
Ixonos development is not a “downloadable program.” The company is in talks with OEMs about licensing it to "leading electronics manufacturers", so we probably will soon be able to see the new face of Android not only on Samsung devices. [ Source ]
