Something that made me think for a long time was that I could not change the icon of Kmail that comes out in the system tray (tray), and since I used a monochrome theme, it looked pretty ugly along with the rest.
Okungenze ngacabanga isikhathi eside ukuthi angikwazi ukushintsha isithonjana se I-Kmail lokho kuphuma kuthileyi wesistimu (ugqoko), futhi njengoba ngisebenzise ingqikithi ye-monochrome, ibukeka kabi kabi kanye nokunye.
