Yupii - a Business Application Framework based on Codeigniter

1. Why did you convert pasted text to uppercase. I want to be small. How do I do that?
2. When I put date (field type DATE), I would like to display the calendar of choice and control. How do I do that?
3. How can I insert files? How do I do that?

I thought that Yupii can do all it, as it can do GroceryCRUD http://www.grocerycrud.com/
