Implement quickswitcher

[jp-hoehmann]

The user should be able to switch to recent profiles (including his own pages) with a single click.

Do you mean user profiles or pages?

[jp-hoehmann]

Both, also groups, apps, games, ... – any profile the user recently looked at.

Currently it takes two clicks to navigate to a different page (navigating to a Profile is not implemented yet, but will require even more than two clicks). This could be fixed by putting the pages into a bar of tabs under the toolbar, however professional users may have more pages than can be comfortably shown in a horizontal bar of tabs, so that is not a solution. Having a sidebar with a full menu is not a solution either, as it waste a lot of space.

This issue is about providing a quick way to navigate to anything the user recently looked at, to make up for the fact, that navigating to another page will probably require two clicks even in the release version (and for the fact, that bringing up a profile via the list of recent searches will require three clicks).

@TGTV any Input on this? I am currently finalizing the project plan for the documentation and this still has no priority.
