I tried the book-details.
After some trouble figuring out how to get it to accept 'My Books' for library name (underscore or %20?) I put in the hex encoded version copied from a show-book. Oddly the titlebar shows it as "My_Books"
Also it's surprisingly rather barebones -- just default columns, no links. I guess this makes sense as accessing other libraries might be slow or complicated (especially for lots of composite columns like me
). Since I only use one library I would stick to show-book.
