For admin users who have been assigned the relevant security right/s (App Bar and Control) there will appear a small Affino-logo-identified box in the bottom left hand corner of the screen. The clicking of this will open up a menu panel which gives you direct control over most of the key attributes that impact what you see on the screen.
The App Bar allows you to edit directly the content you are seeing on the screen - based on that current content hierarchy. You can also access, update and change Design Elements and Objects appearing onscreen. You get access to the various relevant setting profiles, Text Items, Security rights and the like. There are also a couple of session-related variables you have control over, like cacheing and custom CSS / script display.
All-in-all the App Bar is a mini in-context version of the control-side, which gives you immediate access to change most of what you see happening on the screen in front of you.
The App Bar gives you intelligent and immediate admin access to whatever page you are on. It allows you to do all your day--to-day site admin from the comfort of display-side. Of course the display will flip between control and display-side, but all the actions are triggered and returned back to the active live pages.
One of the key aspects of Affino has always been the immediacy of the admin experience - in that you can truly make wide-ranging changes directly and instantly from the various admin and editorial utilities. The App Bar is the key display-side admin utility, and replicates huge amounts of control centre functionality - in as logical and usable manner as possible.
The idea is that once you've been through the process of fully setting up your site, you can then do 99% of your regular admin tasks via the App Bar interface quickly and efficiently.
You should get a fair idea of what the App Bar is about from the above screenshots.
To see this in action, you are best off here viewing a live demonstration - that alone can convey what Affino is truly capable of:
