Some of you may already have anticipated this move. Midori is a web browser, based on WebKitGTK+. Postler is a mail client and also mostly a thin wrapper around WebKit. There’s been a feed reeder extension for Midori for a while which also uses WebKit. The natural evolutionary step is to merge these pieces of code. The few C pieces of Midori will be rewritten in Vala.
Enter Meiruborosuaa, from Japanese メイル for Email and ブラウザー for Web Browser. The name was chosen because it’s easier to pronounce than Midori and reflects the new goals. Work has already started in a private branch and will be moved to the official repository in the following week. Rest assured, existing Midori extensions will continue to work. The new split view where you can see your tabs on the left, your mail boxes on the right and the message or website in the middle however required API additions that extensions don’t use yet.
