[AccessD] Form navigation

Hi all

I'm working with an A2010 application to be used by about 100 users from
different business areas.
The users are trained and will use the app extensively.

It has about 50 forms and a dozen reports. Currently we are using what I
believe is the native switchboard of Access (I didn't build it), but I find
it clumsy, and it takes too much screen estate even though all users are
equipped with 24" monitors or dual monitors. However, the biggest
disadvantage is that once a menu branch is chosen, the other branches are
hidden, so if you are working in different corners you have a lot of going
up and down in the navigation form.

Could anyone suggest a proven alternative? The treeview is gone, I believe,
but how about the ribbon? The users are using some of the general options on
the native band, so how would you combine those with custom options?
Other ideas?
