Counting keywords, please!!!!

Please guys can you add counting keywords function in "Keywords" text area, we are begging for it for a long time.
Here is first example from google search:

i can`t belive adding this to keyword text field is so hard.

Would also love to see counters on the verbose for 'atc' & 'atb'. Thanks!
