Sigil 1.0 now automatically restructures EPUBs
Sigil-1.0 marks a significant milestone in the history of Sigil. The requirement that all epubs be restructured to conform to Sigil's long-standing standards has finally been lifted. Upon initial loading, the existing epub structure will be loaded and preserved in its current state, without any renaming or moving. While the BookBrowser will still display the Text, Images, Styles, Fonts, Audio, Video and Misc "folders," these are now considered "virtual folders" that merely organize the existing resources by type, but do not impose any restrictions on their actual location within the epub. A new Appearance Preference has been added to the Preferences settings that will determine whether the book folder's relative path or its shorter unique name (filename) will be displayed in the BookBrowser. Regardless of the setting, the tooltips in the BookBrowser will always show the file's actual book folder relative path. To distinguish between duplicate file names in different subfolders, the longer path will always be displayed, irrespective of the new Appearance Preference.
