When adding a bill, the people with whom you are splitting should be visible on the the same window
You should not need to click on any button to view the people you are sharing the bill with.

Hey Sanal – with the new form, you can still see the list of involved people at the top of the window (“With you and:”), or as you mentioned, you can click the “split equally” link for something more similar to the old view.
We found that for most users and most bills, including the list of individual users who owe was unnecessary – it was infrequently used, and it just made the form more complicated. That’s why we decided to hide it behind a click in the new form design. Sorry for the inconvenience!
