This should be a $4.99 app on a smartphone and/or desktop and doesn't take up any space.

Related but different better time/social management physical device for cube land would be an Arduino, a button, and an 4-7 color andon tower representing states such as:

- Working

- Lunch or errand (will return)

- Out-of-office (not returning for the day)

- Working remotely

- DND

- Open to socializing

- On vacation

And then a glossary for definitions posted prominently on the cube/office and on the intranet portal personal page. No app, no internet connectivity, no security vulnerabilities, no complexity, and <$20.
