Redesigning the tags screen

[lokesh-krishna]

The current screen for adding tags has a lot of empty space and also is pushed hard to the left of the screen.

A design goal could be to emulate or take cues from the tags screen of Google Keep.

Also when tapping the top-left menu in the main screen, when the menu rolls in from the left with the server info on the top and then below the tags, there should be a button on the bottom with a text like "Manage Tags" and this should bring the user to the new tags management screen where it should be possible to add/delete/rename/move (or sort) tags.
