Thanks for your answer.
I found this website: https://tutsplus.com/course/improve-workflow-in-sublime-text-2/
With help of that video course I discovered the power of Sublime, and I understand why there is no GUI, so I will stick with Sublime and forget UE. I will conquer Sublime and submit it to my wishes.
If we all were the same, then there would be only one person in the world, and that would be me. (Or you.)
All the best,
