Hi. As the welcome announces: "You are in the right place if you have a question or enhancement request regarding Oracle XE", then we propose as users of this good product, improvements, and if we defend our proposal with valid arguments, better.
I cannot conceive that everything in Oracle XE is said and that more and better cannot be done.
In the end, we are members of this community and can suggest based on our experience and needs.
I invite you to participate.
Regards.
