title_body: How do I remove tiles from the Kobo home screen?
upvoted_answer: There is a plugin for Calibre called Kobo Utilities that can dismiss unwanted tiles from the Home screen.
  
  
    The Kobo Utilities Plugin adds extra function to calibre for working
    with Kobo WiFi, Touch, Glo, Mini, Aura, Aura HD, Aura H2O and Glo HD
    eReaders. This will allow changes on the eReaders that either cannot
    otherwise be made or will make them easier to do.
    
    The current functions of the plugin are:  
    
    
    Set/Remove font settings for specific books.
    Dismiss tiles from tiled home screen.
    Update metadata directly to the database on the device.
    Change the reading status.
    Manage series info for books on the device. This is mainly for books not in the calibre library including kepubs.
    Store/record current reading position for ePubs. This can be done manually or automatically when the Kobo ereader is connected. Profiles
    can be used to manage the reading positions of multiple devices.
    Upload/Remove covers for all books in the library. This includes kepubs.
    A couple of annotations options that I'm not happy with.
    List the books missing from the device database. This only lists the books that calibre thinks should be in the database.
    Backup the device database.
    Run integrity check on the database. It doesn't fix anything, but it tells you if the database is OK or not.
    Clean up duplicate shelves.
    Remove annotations files.
    Set "Related books" for sideloaded books.
