(Welcome to the friendly desktop Kubuntu 19.04!)
Here's once again traditional article to help new users use Kubuntu 19.04 for their first time. This article suggests you some stuffs after you have installed Kubuntu successfully. I divided the materials into 3 parts, about file manager, System Settings, and workspace. You will find here quick guides to setup Dolphin as you wish, create new shortcut keys, and rearrange desktop to your needs, and more. In the end, I added short workaround to lock your folders safely using Kubuntu built-in Plasma Vault. Have fun with Kubuntu. Happy working!
