I am:
The beginning of the outsider, the omitted, the omega,
and also of the most-able, the marking, the mega.
The middle of the vision, the view, the vector,
and also of the ribs, the river, and the runner.
The end of the pain, the powerful, and the primate,
and also of the witty, the weary, and the white.
What am I?
Criteria:
green tick: find "I" and all words-to-be-found
additional +1: all words-to-be-found in a line begins with same letter
Hint:
vision: ( (o)
vector: #include
runner: animals
powerful: definition--> with capability
witty: animals + so near, yet so far... ;) READ RIDDLE AGAIN
Enjoy!
