At the moment it is not possible to order the components krunner checks. For example the commandline component has a high priority so that using components like windows or application termination requires more keystrokes.
It would be great for the order to be customisable.

Anyway I second this request: the default ordering completely breaks my work flow. Somehow KDE4 had it right (prioritizing command line and applications over recent documents and folders, for instance).
