Version: (using Devel) Installed from: Compiled sources As the title says, I'd prefer that okteta and kate would show up under the "development" category of applications. Kate is in kdesdk and Okteta will probably move there sooner or later, as far as I understood Friedrich.
The Applications section of the new website is supposed to reflect the layout of the application menu in a KDE installation I believe, especially since ( parts of it ) are generated from the application itself ( not sure which parts ) If this is changed for KDE 4.5, then it can be easily done.
That is true, the categories are automatically taken from the desktop file. If you think that some categories are wrong, feel free to contact the authors or file a bug for the application itself and the website will follow.
