Extension:SubPageList looks useful for Wikisource due to its ability to manage categories where a work has 000s of subpages that are categorised, and displaying categories is burdened and pointless when it is the subpage names that are relevant, and not the work's name.
I am wondering whether we could get the extension installed on Test2 (or another suitable test environment for Wikisource capability) to evaluate the extension, and for those who wish to manage security aspects to also test and evaluate.
