Hi all If I understand correctly orgstruct-mode has much more convenient key bindings like TAB and its variants for cycling than outshine.el or outline-minor-mode which is a big advantage for me. When point is on a heading also the other key bindings are just the same as in Org mode. This was my reason to give up outshine.el and to stick with headings where orgstruct-mode does a good job and to not use lists.
If it is an option that someone reduces orgstruct-mode to only cycle and navigate headings, without all the rest like for example heading structure editing or lists, I would continue to use it instead of outshine.el, outorg.el or even Org Babel for sometimes shared source code files. Michael
