The left Navigation drawer, that opens when the Hamburger menu icon is clicked, is a bit overcrowded.
It has a set of entries that are related to navigation like : 'Home', 'Explore', 'Bookmarks', 'Review' and the rest are
a set of actions that are related to the User - Profile and preferences related.
This task is to segregate them into :
a. Bottom Navigation, and
b. Left Preferences Navigation.
Further, the bottom Navigation will have tabs related to each of the navigation related entries that previously existed in the left drawer:
'Home', 'Explore', 'Bookmarks' and 'Review' .
The screens themselves will not be changed
Suggestion as part of this: When users download the commons app, they might want to see a feed of beautiful images first. So, we could re-arrange them as :
'Explore', 'Contributions[Previously "Home"]', 'Bookmarks' and 'Review' .
