Currently, it seems that Kickoff lacks the functionality to launch an application as another user via Sudo/Polkit like the "Run as Administrator" functionality in Microsoft Windows(R) Start Menu. Supporting it would cease the need to run kdesudo/pkexec via Krunner or command-line.
(In reply to Ｖ字龍(Vdragon) from comment #0) > launch an application as another user via Sudo This is officially unsupported everywhere, and Dolphin and Kate in fact don't even run using sudo due to security vulnerabilities. So we won't be able to add a feature to make it easier. :) > via Polkit This is unnecessary, since the point of Polkit is that you run apps as a normal user and are prompted by the app itself only at the moment when elevated privileges are required. The app handles everything.
