Intuitive means it makes sense instinctively. Touchscreens with pinch to zoom are a good example of intuitive UI design. Children can pick up an iPad and learn to use it quickly with no instruction. That's intuitive design and of course it exists.

Is your custom script heavy system more efficient for your workflow? I'm sure, but picking it up out of the box it's going to be horrible for a new user, they will be slow on it, it'll be unenjoyable and annoying. That's my point really, every Lemmy app I tried was unenjoyable and annoying. Sync on the other hand I have never used before, but out of the box? It works, I'm happy browsing with zero issues or errors or struggles within minutes. That's intuitive design.
