As the mobile Web matures with phenomenal user growth, the Dolphin HD browser introduced today two add-ons that bring the power of apps to the mobile browser.
The new add-ons for Evernote (download) and Skitch (download) take previously app-only features and port them directly into Dolphin HD for Android only. Unlike most Dolphin HD add-ons, neither of these can be added from within Dolphin. You must go through the Android Market links above to get them.
Taking features from an app and adding them to a browser is common on PCs, but it's still fairly rare in the mobile world. The Evernote add-on lets you highlight text from a Web page and copy it directly to your Evernote account when you tap the Evernote icon, which can live either on your address bar or in the sidebar on the right. It lacks the ability to add richer content, though, such as images or videos.
The Skitch app has a fair bit more going for it. Skitch is a mobile service that lets you edit images and screenshots on the fly. Once installed, you tap the red-heart icon on your right sidebar to activate it. It'll request your log-in credentials or guide you through the registration process, if you don't have a Skitch account. You then grab an image or screenshot, and can edit at will. Tools include things like modifying the image, drawing on it, and adding text.
Since the rise of the mobile app, there's been a lot of disconnect between apps and the mobile browser. A link to a site that also has an app will often take you to the URL in a browser instead of opening in the appropriate app. So, if you click a Flickr link in Twitter, it will jump to the Flickr site instead of the Flickr app. Apps are often described in mind-numbing techese as "verticals," where the experience of the app is self-contained and not broad across other apps and services. Add-ons such as these two could indicate that mobile-browser makers are going to spend 2012 looking at how to more naturally integrate apps and mobile browsers.
