Hello! I'm new to this forum. Congratulations on the wealth of information, I've yet to digest it
I wanted to suggest three Calibre features, I don't know if this is the right place or if I should go to their development pages, but I had problems signing up there last time.
Anyway...
Suggestion one: when you add duplicate books, a dialog appears where you can choose which ones to skip or add anyway. I propose you add a "merge" button on that dialog, or even better, several buttons with different behaviors.
Suggestion two: there are options I ALWAYS use when I add a new crop of books. I would like being able to set them as default. Case in point: I NEVER want to import tags or star ratings from the books I find in the net. I use my own ratings and tagging systems. So I always use the options to remove tags, and reset ratings to zero (which in my system means unrated). I would love that happening by default.
Suggestion three: Ignore non-alphanumerical characters in title or author sorting, by default. Sometimes, a leading character which is neither a letter nor a number disrupts sorting.
Thanks!
