Tip of the Day
The Eclipse Tip of the Day framework enables users to see Eclipse Tips during startup and enable extenders to provide tips for their specific bundles.
The TOTD UI looks like this:
TipProviders are selected based on their importance in the current context. For example, if the Java perspective is open, you are likely to get Java tips. If the PDE perspective is open, you are likely to get PDE tips.
The Tip of the Day feature is available in the nightly builds. After restart the framework should fetch some data from the downloads area and present 4 tip providers with new tips.
I would appreciate your feedback on bug 
1. Help/Install new software 2. Add this repo http://download.eclipse.org/eclipse/updates/4.8-I-builds 3. Uncheck "Group Items by Category" 4. Search for Tips 5. Install and restart.
Extending IDE Tips
Extenders are able to provide a TipProvider class that can serve Tip objects. Each Tip can provide a link to a website OR a HTML description and an Image URL.
Tips can be retrieved from the Eclipse Wiki. The TipProvider may read tip URLs from a page and create Tip objects from a link. Examples in the framework provide tips from the following page:
Tips can be retrieved from Twitter using the embedded link.
