2- A plugins visual graph in dashboard where you can see what your WP site can do, and see the plugins as "extensions" with their roles.
Sometimes you don't all the features WP or the installed plugins have, so a visual board can help:
-Know what you can
-Know what you can't do
It's easy to see how a plugin can have a duplicate function, or extensive to what you have right now.
Something like a lego block, and you can see how everything connects and talks to each other (better explained in part 3/3)
