I use wikidoc internally for notes, but also externally to document my software product.
I recently "upgraded" to "hogfather", and in the process lost my side menus. I hab been using a template called "round box", which is no longer supported.
I had to turn of the sidebar displays because whenever I click to edit the main text, the sidepanel also appeared as editable.
I chose wikidoc because it uses flat text files rather than a database.
