I would like to hear your insights about strategies on organizing menus. I mean two main approaches: having each menu header as an individual Drupal menu vs. having all menus grouped as one big menu, perhaps named "Main menu".
I built quite a large site where I had to use such modules as OM Maximenu, Taxonomy menu/Taxonomy menu trails, Menu Block, Sitemap, DHTML Menu. Without much knowledge about Drupal and the consequences of my choice, just to keep my progress on, I took my liberty to sometimes put a group of menu items as individual menus, sometimes I grouped them together (this was the case of Taxonomy menu and Menu Block where I could define the level at which menu starts).
Then, when I installed Sitemap I saw that my menu organization revealed to public. This was also a lesson.
Although everything works OK, I don't feel alright with this kind of mess. Especially, after some time I know I will have to do a repetitive research on how a particular menu is built, rather than have it intuitively solved right away.
My question: What is your preferred way to build and organize menus with rich taxonomies and complex view-based menus (OM Maximenu)?
