automatic isearch-mode in org-goto and org-remember

[Piotr Zielinski]

Hi,

The following lisp code turns automatic isearch mode on (as in
Firefox) whenever you navigate an org-file using org-goto or
org-remember.  It is useful especially for finding headlines when the
org-file is long and has a deeply nested structure. The isearch-mode
is modified so that it searches only headlines (even invisible ones)
but ignores normal text.

The function local-move-tree uses (the enhanced) org-goto to move the
current tree to the selected location.  It is useful for organizing
your org-file; when many items accumulated on your general todo list
(eg. after using org-remember a lot) and you want to dispatch them to
the projects they belong to.

Finally, the newest version of  org-mouse (0.17) allows you to toggle
checkboxes [X] with a single mouse click.

this looks really great.
