Business problem

Each user can create at most 100 Custom Inboxes in a workspace, and the limit can’t be raised. Workspaces with many channels, teams, or segments can’t create the dedicated views they need, such as one per channel. Once the cap is reached, users can’t create any more inboxes.

Desired outcome

Allow a higher Custom Inbox limit per user, ideally configurable per workspace or plan. Keep the left sidebar performing well with a larger number, for example with search or grouping.
