@Prondubuisi You got it! The Project is all about extending the application inside the <pagelist /> that will have no params initially.
@Samwilson I've question about the default numbers which are invoked will initially refer to the Pages (1-n). Can we not create separate list of pages on the sidebar to pick the pages.?
And afterall on the basis of textlabel i can pick the pages and update their Index number.

Respected Mentors! I am interested in this Project. Continuing my flow of writing some few more words i want to ask while extracting the different meta-info as a params from other formats like pdf, or djvu is it possible to add these keys into the OOUI. As of now we need create a widget for Index Page Pagelist. I would like to contribute in creating a scalable OOUI widget which basically transluent from that Interface.
