Search is worse with v5.6.0

New Inkdrop user here, while this issue has been solved all my initial impressions with regards to how I will use Inkdrop relate to broadly to search:

  1. Is INBOX a special notebook? - after reaching the search documentation and syncing a few notes between mac and android clients I was unable to replicate what I was seeing in the sidebar
    All Notes (4)
    Inbox (3)
    Search Term: book:Inbox (while case sensitive returns 0)

  2. While the addition of To-Do Status Plugin changes the status of notes when the associated To-Do item is closed/completed I am unable to determine with or without plugin if it is possible to search for notes that contain to-do checklist items.

  3. Saved searches - let’s say I have a somewhat complex search criteria for notes in a notebook containing these words and tags but not other ones, is it possible on any of the Inkdrop clients to save these searches for reuse later?

Thanks Josh
