Improving KDE
Work on improving KDE by integrating Konsole, KDevelop, Kate, Kile, Dolphin, Kexi and Falkon and KDE Connect into Kontact. Make it work fast and secure. It should be fairly simple to add links to start the applications in the Kontact window. At least add Kate, Dolphin and Falkon. Of course, you will still be able to open those applications separately.
Get C++, QML and Javascript (codejs) installed in your local development environment and then check out a branch of the KDE code from GitHub. Start working on integrating these applications into Kontact.
Create some really excellent documentation to teach people to use Kile and Kexi in their workflow. I’ll be working on that here at homeoffice.studio. I’ll have to learn how to do it first. You can start searching and investigating how to use Kile and Kexi while you develop your own holistic home office.
