Protip: Use krunner (Alt-Space) to launch applications once you know their names. It has autocompletion and many neat features such as web shortcuts: Type gg: or dd: <search terms> to open a tab in your configured default browser with Google or DuckDuckGo search. Not very discoverable but very convenient. You can also create your own web shortcuts in KDE system settings.
krunner also supports opening Kate (the KDE editor, roughly similar to Sublime Text) sessions directly.
