Use CM K2 Inline to customize your K2 back-end item list page:

- Show/Hide columns you want to see (title, published, ID, featured, etc.)
- Edit extra fields inline
- Batch edit extra fields
- Order columns as desired

What does this all mean:

- You can have a simple & clean item list page
- Simplify the item list page (workflow, pefect for low-tech clients)
- batch process (filter items then modify multiple items at once)

Best of all they offer clear & detailed instructions:
cm-k2-inline.readthedocs.org/en/latest/

One more best of all, I posted a few questions and suggestions on the developers forum and received a response in less than 24 hours.
