UI/UX Suggestions

[NachoPal]

• Sticky side bar and top bar
• Add a back button in each Post, Proposal, Treasury, etc view
• Add a Status filter to Latest Activity
• In the News section, tweets views feel too big
• For a the individual Proposal, Referenda, etc.. views it is not clear their kind, and also the side bar menu is unselected. It would be good if there was a heading making clear the view is a Proposal, Referenda, etc. In addition, the corresponding section in the sidebar should be selected.
