Main template UI and Composer UX

In response to several feedbacks related to the general layout and the composer experience, we prepared a few mockups to highlight some UX improvements we'd like to discuss with you.<p>Main feedbacks gravitated around the possibility to have as much space as possible for the main content view, a clearer navigation menu and clear distinction between navigation and widgets sections. </p><p>Looking at the near future, we tried also to imagine how to organize the space in the navigation sidebar to have enough space for groups and lists.</p><p><br/></p><p>In particular, we spent some time thinking at an altenative UX to compose a post. This is for different reasons:</p><p><br/></p><p>- We're working on flexible boundaries / lists - and a dropdown is not enough to let the user work with such granular permissions levels</p><p>- We want to have a composer box that incentivate also toughtful posts, not just toots/tweets</p><p>- We want to have a unique composer box that works in any situation (actual fullscreen mode is buggy)</p><p>- We still want to be able to compose a post while scrolling the feed or reading through the comments in a thread</p><p>- The composer box should not be always visible on the page, but it should be 1-click away to start composing a post (with keyboard shortcut also)</p><p>- The user should be able to work on different drafts</p>
