-Clicking "New Note..." clears the search and sort, so the new note comes out first in the list.
+The "search and sort" only occurs when the search term or sort order is changed. So, clicking "New Note..." will safely make the new note come out first in the list.
+
+The user starts-out as anonymous, so his bin id must be saved to access the bin again.
+
+The user may type-in his username/password to sign-in; in which case a list of his bins can be opened. Note that since the user is signed-in, his bins may have a human-readable id in addition to a regular unique id, since it only has to be local to the user, not globally like anonymous bins.
 
 ## TODO
 
-- provide handlers for events
+- prepend "new note" to notes list, not append
-- get/set state from/to server
+- focus new note upon creation (surprisingly hard to do "the right way")
-- add paging
+- optional user sign-in
+- create new bin
+- open existing bin using browser `location`
+- add pagination
+- search term highlighting in result note text
