# Introduction
Avoid having multiple `isDefined` definition across our pacakges
Also avoid importing `isDefined` from `twenty-ui` which exposes a huge
barrel for a such little util function
## In a nutshell
Removed own `isDefined.ts` definition from `twenty-ui` `twenty-front`
and `twenty-server` to move it to `twenty-shared`.
Updated imports for each packages, and added explicit dependencies to
`twenty-shared` if not already in place

Fix#8758
This PR is migrating the recoil component state from v1 to v2 for board.
It also now share some states and logics between board and table,
further can be done later.
Lastly this PR fix an issue since the PR #8613 that was treating
no-value as a normal record-group.
Fix#4244 and #4356
This pull request introduces the new "view groups" capability, enabling
the reordering, hiding, and showing of columns in Kanban mode. The core
enhancement includes the addition of a new entity named `ViewGroup`,
which manages column behaviors and interactions.
#### Key Changes:
1. **ViewGroup Entity**:
The newly added `ViewGroup` entity is responsible for handling the
organization and state of columns.
This includes:
- The ability to reorder columns.
- The option to hide or show specific columns based on user preferences.
#### Conclusion:
This PR adds a significant new feature that enhances the flexibility of
Kanban views through the `ViewGroup` entity.
We'll later add the view group logic to table view too.
