1. Please have an option to not request confirmation of deleting ebooks on next sync. It would be nice to be able to set tags to delete ebooks when I'm at my computer, then later on sync from somewhere else in the house without having to sit down at my computer and confirm that I want to remove ebooks. Say if I'm reading in bed and finish my last book, then I should be able to update my library without getting up.
2. Also, I'd like to be able to keep a list of which ebooks are currently on my device, but that's not working for me. I created a custom column called #ondevice and have reading list plugin update this column automatically (you can see the options below), but when syncing, calibre freezes for too long for this to be useful. This may have something to do with my having a large number of documents on my tablet. Basically, I want to have a list of books that are on the device, books that will be removed, and books that will be added (I'd like to use the replace contents option, but I don't want to remove books that were downloaded via the content server or from other libraries).
