While my laptop's screen's big (17.1") I often found that I could use a little extra space for some of the Kontact modules, for example Akregator and KMail. Idea: a button labeled "Kontact" or "Modules" (with the Kontact/Summary icon) could provide a drop-down menu to easily and swiftly change between Kontact's modules. Usability: this way I could add the button to the toolbar and finally hide the "modules bar" (sorry, don't know how it's named), gaining this way some extra precious space. Reproducible: Always
