Title frames are pretty inadequate for anything other than a home movie, in my opinion; though they're the in-software topmost solution. I don't think I'm alone in that notion.

Personally, I usually just work up an image overlay in other software, like Krita if you want something from the KDE set, or Blender, or some other tool, and export it in a transparent-background format that Kdenlive can treat as a clip, like EXR or PNG; then I overlay it in the timeline. It works fine for videos and gives you a lot more stylization options.
