This is more convenient than Emacs bookmarks, but still breaks org-mode to
a certain extent: all non top-level headlines below point are hidden. At
least for me.
Org-mode has very precise control for situations when a jump into invisible text happens, for example by isearch or by bookmark-jump or saveplace. Take a look at the variable org-show-siblings and set a special context for bookmark-jump, that should do it. This will work for both saveplace and bookmarks.
You can do this with customize, or just like this:
(setq org-show-siblings '((default) (isearch t) (bookmark-jump . t)))
There are companion variables, they are all in the customization group org-reveal-context.
