It is.

First, I adore calibre and was extremely glad to find the companion app since it makes reading and adding my fanfics and various novels so much easier. Fanfiction reading especially is quick and ever-changing, and selecting one book and deleting it is a little tedious. It's more frustrating if the book is in the middle of the pack and I have to scroll all the back to the middle for the next deletion.

My first request is this: a mass select-and-delete option.

First, you can delete in bulk easily when connected to calibre as a wireless device. Run a search in the library view for the books you want to delete, something like "ondevice:true and tags:???", select the books, then hit the delete button. When prompted, push the "delete from device" button.

If your search for what to delete is based on tags then you might be able to do the search directly in the device view.

OK, to your suggestion: how do you see it working? Do you want to delete all the books in the displayed list? For example, do a search or group on something, then delete all the displayed books?

Do you want to "mark" each book somehow and then deleting all marked? I am not sure I see the difference between selecting a book and going to book details to delete it. Ahhh, I see, there is a bug here. The booklist is positioned to the beginning when a book is deleted. I will fix that so that the booklist is positioned approximately where it was. Does that solve your problem?

My second request deals with the viewing of books with multiple formats in CC. Is it possible to just have one "book" in the gallery and when you open the file to read the book you can view what formats are available? Something like how CC operates when its connected to the content server and the option it gives you to download/read a book from the little drop-down menu at the top. It'd be easier to scroll through CC with only one book than to see doubles of everything that has both a mobi & epub version.

Unfortunately this isn't possible, or at least not possible in reasonable development time. Calibre's device subsystem is built around the idea that a format (book type) is a file, and that formats are independent of each other. When we first built CC we tried to use the UUID (unique book id) as the identifier. We went down a rabbit hole trying to maintain a map between the "device view" of the books in CC and the "book view" that you are asking for. All sorts of things went wrong. I tried again when I added the metadata cache optimization, and I failed to make it reliable.

Out of curiosity, why do you have multiple formats of the same book on the device?

One thing that might help: create a "formats" custom column and add that column to CC's grouping drawer. Once you do that you can ask to see books containing one format or the other. A long press on a format name (e.g., epub) would do the equivalent of creating a virtual library containing only that format.
