In general Eva had no prob to handel an articles. Every parameter is accessible.
Only the read-more functions is a little bit difficult to use.
Now it is a little bit complicated to explain.
If Eva writes an article the focus is usually in the textarea.
To add the readmore “hr” the cursor/focus has to be at the correct position. To select the readmore button she has to leave the textarea, so the focus in the textarea is lost. There the readmore “hr” is automatically added at the bottom of the article text.
Evas solved the problem by cut and paste the readmore “hr” at the prefered position.
Conclusion: A little bit complicated but it works
