Swiping in book details means going to the next or previous book as defined by the current book list display. This is what I think you are asking for.
The infrastructure stuff refers to being able to mark a book read in CC and have that information transferred up to calibre, stored in a custom column of your choice.
You can already hide books that match some value in a custom column. Long press on the value in the grouping drawer and select "not matching".
As for a tip mechanism: thanks for the good words. We are very happy to have satisfied users.
