As far as I know, there's no option to open links in feed with in-app browser. Only web module allows to open links within app. Ability to open links with in-app browser should be added. I managed to show Facebook comment system in article but cant comment because all button clicks are opened with third party browsers. If there was an option to open the click with in-app browser, I would be able to login to facebook from within appyet app and leave a comment. If I'm not wrong, unchecking "Open in Default Browser" won't allow us to open links in feed with in-app browser. default browser means, in android, we can set a particular web browser as default browser and whenever we click a link, the link will open with that specific web browser.
