Categorization and left column

[Seafnox]

If in the project was created too many models, top menu become too overloaded and ugly to view.

You can creaqte left menu and move models into it. It is always help to create category.
For example:
User, Role, Rules - it could be unite into "user managment" category

In models (or in config/cms.js into model description) can be added special field: cmsCategory, which could be contain name of the category
