The user interface is garbage (for lack of better words). Having an autohide bar along with a separate page for the table of contents. Instead of using a sidebar for showing sections, it displays a separate page, which is incredibly dumb. Michael seems to use this as nothing more than a parser for epubs, and does not give a damn about continued usage or usability. When you launch fullscreen, it doesn't expand either and the content is stuck in a box. The options are garbage. This does not deserve any high ratings from actual users.

I advise everyone to install calibre instead of putting up with this waste of time garbage addon.
