Streamline login flow

[sshein]

Problem

The current login flow is clunky — users have to log in and out repeatedly to switch between different groups, which creates unnecessary friction.

Proposed Solution

1. Dashboard on login: After logging in, users should be taken to a dashboard that displays all of their boards in one place.
2. Per-board collaborators: Instead of adding collaborators at the group level, collaborators should be added to each individual board. This removes the need to manage separate group memberships and allows finer-grained access control.

Benefits

• Eliminates the need to log in/out to switch between groups
• Provides a unified view of all boards upon login
• Gives more granular control over who has access to each board
