KoboTouchExtended is a free plugin for the Calibre ebook organizer application that adds an extended driver for the Kobo Touch, Kobo Glo, Kobo Mini, Kobo Aura HD, and Kobo Aura ebook reader. FWIW, the excellent Kobo Touch Extended plug-in for Calibre makes managing Kobo devices a trivial matter. Simply identify the Calibre column that contains the bookshelf label and the books are instantly categorized on the device. Adding/deleting multiple books to/from the device using Calibre is equally easy. Open Calibre, and install the KoboTouchExtended plugin: Click the “Preferences” button on the toolbar. Under the “Advanced” heading, click the “Plugins” button. Click the “Get new plugins” button. In the “Filter by name” field, enter “KoboTouchExtended” and double-click the result to install it. Restart Calibre. Apart from the plug-ins I mentioned above, I also use Kobo Utilities and the Kobo Touch Extended driver, and View Manager (which is a godsend for keeping everything in order - I sort by author sort, then by series & series index, subseries & subseries index and then by title).

If you’ve read any of my reviews for Kobo eReaders lately, the Kobo Mini, Kobo Glo, and Kobo Aura HD, you’ll notice that I complain a lot about how Kobo chooses to format ebooks.

My main issue is with all the wasted space. Kobo insists on adding a huge bar at the bottom of a page to display page numbers, and another huge bar at the top of the screen to display the title (seriously Kobo, like I can’t figure out what book I’m reading that I need to be reminded on every single freaking page).

There’s also the fact most Kobo ebooks have spaces between paragraphs instead of indented paragraphs, which wastes even more space. Personally I just want my ebooks to look as close as possible to the paper books I’ve been reading my whole life, which means indented paragraphs and justified text.

And don’t get me started on how much I hate the long paragraph bug that makes it so there’s even more wasted space at the bottom of the page for certain books and fonts.

The irony is that Kobo’s ereaders offer more layout and font adjusting options than any other brand, but when it comes right down to it there are too many limitations and variables to make good use of the settings. In fact I can’t think of an ebook reader or app that annoys me more than Kobo’s software.

Luckily, there’s a great free ebook tool called Calibre that you can use to re-format your ebooks to have more control over formatting. With the proper settings you can easily minimize wasted space and remove spaces between paragraphs. You can even get rid of the entire big bar of wasted space at the top of the screen (unless you are running firmware version 2.5.2).

Kobo Formatting Tip: Minimizing Wasted Space

Awhile back a reader named Evenft left a comment about what settings to use with Calibre to minimize wasted space. Here’s the procedure below, and here’s the link to some pictures showing the settings in Calibre if you need a visual.

You can use Calibre’s conversion feature to change the CSS settings in an ebook. If you are converting regular DRM-free ePubs all you have to do is import them and follow the directions below. If you want to convert purchased ebooks from Kobo you’ll have to login to your account and download the copies first, which requires using Adobe Digital Editions, and then import them into Calibre to convert them. You can also easily remove the DRM if you choose to make it so you can read your ebooks on other ereaders and apps.

– After importing the ebooks into Calibre, select the ones you want to modify and choose “Convert books”.

Kobo Touch N905

– Make sure the output format is ePub.

– Click on the “Look & Feel” tab. Enter the following code into the Extra CSS box:

body {orphans: 0; widows: 0}

– You can check the box to remove spaces between paragraphs too.

– There’s also the option to remove existing CSS properties for fonts, margins, and padding under “Filter Style Information”.

– You can choose to set default line spacing to 0% and margins to 0 pt as well.

Some of these settings aren’t needed depending on how the ebook is originally formatted. The two most important things are adding the extra code in the CSS box and checking to remove spaces between paragraphs.
