AMZN Merch Keyword List Feature

Allow me to store multiple lists of keywords for niche research. The feature should allow me to give each list a name. It should also allow me to add multiple keywords, long-tail keywords to the list via a comma separated list. I should also be able to add a keyword via a text box. I should also be able to copy keywords to the clipboard, either individually or ALL in the list.

Upon viewing keyword the list should show me the Search Volume on Amazon for each of the keywords. A button to trigger retrieving search volume is okay of that is better for performance of the system.

I should be able to manage the keywords in the list.
