Samsung MultiWindow is a very nice feature on Galaxy devices like S5 and Note 3. Too bad that it is limited to Galaxy devices only. But this is not valid anymore with 3rd party application ~ MultiWindowSidebar. Yup, you can enjoy it on all Android 4.0 devices now. Of course, it won’t be like the exact same Samsung MultiWindow since it is a very new application. But no harm to try it and wait for future version for more features and goodies.
