Background

Since Konqueror 17.08, konqueror is a single application, introducing unfortunate regressions.

Regressions

Resource consumption

The best practice would have been for each window, and each tab to be a separate process (something done by other browsers)? Instead, we now have a single process for everything!

Multiple desktops

Cannot easily distribute Konqueror windows on different desktops.
Launching konqueror actually brings a previously opened window onto the current desktop.

KDE Plasma Activities

Closing all konqueror windows within a single active KDE Plasma Activity does not end the Konqueror process. Konqueror is still active in the background in situations where a previously active Activity was closed with Konqueror sessions running.
