Thanks! Just installed it and the new additions seemed to work well, and the 'short_form' option was one I'd considered asking for, so that's great!. One recommended tweak - I accidentally deleted my config file, so had to re-create it from scratch. Images weren't showing because I forgot to set the $config['web_dir'] variable. I just set it to:
$config['web_dir'] = './';
to fix it -- perhaps ./ should be the default here, since 95% of the time index.php will be launched from the same directory as the rest of the related php files?
One problem I'm having is related to Android/Aldiko - my brother is an Android user. Once Aldiko is installed it associates the 'application/epub+zip' mimetype to itself, and will load the epub once it's downloaded. I have the mimetype correctly configured on my web server, and if I just manually go to the URL of the epub in the browser it downloads and launches Aldiko. However if I try to load the epub using the PHP server the download fails. Android just says the title of the download is <unknown>, and that it was unsuccessful. I haven't tried pcaps or anything like that, but I can give it a shot if need be.
