I can fill in bug/wish reports about what I don’t like:
*. as ‘average’ user as ‘settings’ I consider everything what’s not in ‘add new Book’ workflow GUI if I’m unable to do everything in one screen. For example when I start fill new book data I realise, that I need to go to ‘management’ (of plugin?!) to fill something – that’s awkward… I understand ‘settings’ (of something) as place, where I ‘set-up’ my system one time forewer. If I need to go forth-and-back it’s not ‘settings’ but ‘custom / options’. But… maybe I’m wrong.
*. what for is ‘subtitle’? if it is second part of bookTitle – visually it’s to far from Title now… usually book titles are composed of 2 peaces naming.
*. if book title is long now – text owerflows in page grid-view
*. what to do if authors are more than one and they are not the same as WP user?
*. some CSS style values (presumingly all ‘padding’) are tooooo big, spaces between elements eating workspace and could be at least 3 times smaller.
*. for premium? it would be nice to have import/export option – sometimes it’s more ease to fill plain text (csv?, json?) than jump thru all those fields.
… and thank Yu again for this wanderfull plugin.
