1. Are you saying the notification icons for mobile and tablets (Smart devices) is not already built in?. Then how are people to know they have email, friend request, global... on a smart device?
Is already built-in but there is some overlapping which hide by top bar and we are fixing the issue.
2. CSS, could you direct me to where I can find the procedure to create this config file for future. Thanks.
Actually there is no configuration/settings. All you need to do, as just I said before
1. Add a css file named "custom.css" at root/templates/socialize/css
2. Once you created the css file then you can override any styling here
