Multy-level structure in Navigation for Web-(and wiki-)publish

Dear Bizagi-team,

from what I´ve seen with the web publish, only the last level of processes has an "+" on the left side next to the process name. Since process can have a lot more levels to it, I think it would be quite convenient to have multiple levels up to a certain amount depicted in the navigation. The process structure can be quite confussing otherwise.

Same applies to the wiki-publish I assume.
