Add me to the list of people who would like to see profiles implemented.
As a Google user (both personally and at work), the capacity to split my browser life into to distinct "experiences" is so valuable. When I use Chrome, separate (and synced) profiles mean:
- Separate Google logins, with no confusing switch between user accounts (e.g. being logged into YouTube personally and Drive professionally, and then having to switch back and forth)
- Separate password vaults
- Separate histories and bookmarks
- I can save credit card information in my Personal profile and not have it in my work profile
I'm sure there are other reasons too, but they're some of the main ones.
