by the way: take a look at konqueror...
.. the browser that has had unlimited window splitting capabilities coded in 1999 and is the actual origin of them blink/webkit HTML engines. It would very much welcome new maintainers that could improve usability for modern usage scenarios or port some of the features that went into falkon..

Konqueror is a well-established and powerful web browser, but it is anything but lightweight. On my Ubuntu, upon startup Konqueror alone takes 170 MB + klauncher 40MB + 2 * QtWebEngineProcess 92 MB of RAM. Meanwhile Split Browser on startup takes 90MB + WebKitWebProcess 80 MB of RAM. Also Konqueror is tightly coupled with KDE and it is not easily portable to Windows/Mac OS. If there was a lightweight Konqueror version (preferably based on KHTML/WebKit), I'd like to contribute to it.
