Calibre 2.73 eBook Manager Allows Import and Export of Column Coloring Rules

Calibre 2.73 is here exactly one week after the previous point release, namely Calibre 2.72, to add a bunch of interesting new features, such as the ability to hide row numbers in the main book list by using the new option implemented in the Look & Feel section of the Preferences dialog. It’s also now possible to import and export column coloring and icon rules, but it looks like the Edit Book component received the most attention in Calibre 2.73. For example, it lets you bulk change file extensions for chosen files just by right-clicking on the files selected in the file browser.
