Post unread filter, swiping single post, profile counter, approval for external links

Sharing list of some suggestions:

• we already can see the indicator how many new posts are Unread in Spaces but maybe it would be good to have a filter allowing to view Unread posts only (toggle) so it is easy to focus Unread posts.

  Unread posts could also have a small icon showing status Unread.

• when using the Forum View for posts and clicking/viewing a single post on a screen it would be nice to move to the next post thread without going back in a browser rather to swipe left or right to move to the Next/Previous post.

  Also when viewing a single post in a popup window it would be nice to move to the next post by swiping Left or Right.

  This would be really userful for Mobile devices.

• Additional separate section could be added for the Leaderboard to see how Admin/MODS are performing - this section could be visible to All users or for Admin/MODS only. This might be beneficial when there are many MODS/Teachers etc

• Add User Profile visits counter visible for the All/User/Admin only to see which User Profile is popular (especially for is Public fCommunity)

• Implement approval for posts with external links - when this is Enabled by Admin all posts (in a selected Space) with external text (a href=): http*: links/domain needs to be approved by Admin before being published.

  It would help reduce spamming method with suspicious/unapproved links.

  Currently user can submit a post and Space users will get the email notification with the message and external link we dont want to distribute.

  Note: some links/domains could be whitelisted by Admin and users still could use: youtube links without the Admin approval.
