read my last post in there . wht is normal in one countrt can be offensive in others . <| sep |> I cannot find a zoom sensitivity I like . 400 dpi 2 . 2 sens 1024 x 768 Current zoom sens . 81 <| sep |> Calibre DeDRM plugin will wipe DRM out of any book from almost any source simply by importing the books into the calibre library with the plugin installed , and lets you convert between formats very well too , in case you ' re interested . I run everything I download DRM ' ed or not through calibre to make sure covers metadata tags categories are all set up before I add it to whatever reader device I may be using . Purchased from iTunes or Amazon ? Download into app on macOS , find the file in the hidden proprietary libary on the HDD , run it through calibre , add the new file back out to iBooks Kindle devices , remove the original DRM ' ed version and leave it in the cloud . Great library feature that allows you to combine multiple formats under one set of metadata and manage a whole ton of other stuff . Highly recommended . Calibre ebook . comDeDRM
