Found this site while searching for the word I needed.  In case it is of help to others in the future, the word I was looking for was "facilitator".

Word to describe "a person who is only wishful to help others and cares little about themself"?
Currently, Tapping on the same Tab (in which user is working), The App moves to the very first page of that Tab.

I want to disable the tap event on the Tab in which user is working currently.

Any Hint?
