# Changes 0.3.1

- Add Layout API and let Menu use it
- Add DragData (for float, double, int, etc)
- Add IO Delta calculation to not require a users delta value
- Add Config Var for SLider drag min size
- Remove Hid::Ref input of Containers as IO DragApi is used
- Containers that accept input will require an ID to function
