It's pretty amazing that you can develop an app using KDE's libraries in KDE's IDE, have wonderful artists make your project artwork in KDE's painting app and edit a video about it all in KDE's video editor. The number of organizations that could tell the same story can be counted on one hand. The scope of what the #KDE community does is stunning.
@EikeHein I love KDE, but it's worth mentioning that the program you developed in the KDE environment works perfectly fine if someone uses it on Gnome, XFCE, Awesome, i3 or whatever. It is a truly open ecosystem.
