It is also because Calibre hosts a wide array of features that make it convenient to organize your ebooks.
And whats more, it is a cross-platform software.
There is no visible control in that internal reader.
Perhaps it is designed in that way so that users can read any ebook without too much distraction.
Even more options are available in the preferences menu.
you’re free to also create new color schemes.
Note that the preferences of the reader is different from the main preferences.
If you pop launch the latter, you will see a different set of options.
For example, you might change the look and feel of the main window.
it’s possible for you to also set a folder to be monitored by Calibre.
Calibre will also alert you whenever it detects duplicates but only after you enable it to check for duplicates.
