Manual ordering of books

[xSamel-The-Camelx]

My books in shelf view are out of order and I would like to be able to manually move them around please.

This brings into the picture the whole idea of sorting. Currently the order is just the order they are encountered in os.walk. I remember in other programs they have a dropdown with different ways to sort, one of which being manually, and as you switch between them it changes. I don't really want to have a stateful dropdown.

Maybe a pinning system, kind of like the Windows taskbar, where a program can be pinned or not. So if you drag a book cover it will pin it in place, and to indicate this we could have a different background colour or a pin icon. We'd also need a way to undo the pin, potentially in a right-click context menu.

If a user wants the books to be ordered in a particular algorithmic order, it would be annoying for them to have to do the pins. So in addition in customisation dialog we could have a way to select the sorting algorithm used (if any), which will apply when you save and on launch. But I guess the pins will persist in the same position. There could be a "clear pins" button there I guess.

Implementation steps could be:

• [ ] Drag and drop functionality to reorder, no persistence
• [ ] After manual reorder of an item, put in save data "pin pos" with index order the book was dragged into
• [ ] On shelf view populate, attempt to take into account this "pin pos" data (persistence)
• [ ] Shelf view cover right-click menu with just an "open book" action to start with
• [ ] "Undo pin" action in cover right-click menu for books that are pinned, "pin" if not (to pin it in place)
• [ ] Visual indication that a book is pinned
• [ ] "Clear pins" button in customisation dialog
• [ ] Sorting algorithm choice in customisation dialog, apply on save if changed
• [ ] On shelf view populate, sort it according to the sort algorithm the user selected

Do tell me if I'm overcomplicating this and you can think of a simpler way :-p
