Thank you, KK.
I am still looking for more feedbacks and from other members as well, because it is important to know what is best for the people.
Today I am making things even more easy to use - welcome <cms:get_help /> tag. I let it present itself on its own
All it takes to get help on another tag is to change value in querystring -
If there is nothing in the querystring, then there is no output and we can resume working on our page. Of course we can place <cms:get_help /> tag anywhere on page top or bottom, for uninterrupted work. Internally, it works very simply and piggybacks on 'help' parameter addon.
