Linked docs from within Evergreen, based on the specific function you're trying to do
Make it a quick reference
The documentation as the resource that front-line trainers use first, rather than creating their own manual
Better mobile interface (especially with those screenshots)
How-To videos embeded in the documentation
A lot more screenshots, visual aids help
More accommodating for different learning styles, especially visual and auditory learners
Be able to choose which version you're searching
Better index
