TAB Key control to move to adjacent cell [FEATURE REQUEST]

[Tropicalrambler]

Current Behavior: When in edit cell mode, TAB key does not do anything. User must press ENTER, and then tab moves to adjacent cell.

Desired Behavior User should be able to customize the column with a property named "tab_exits_cell" so that if true, when editing pressing the TAB key moves out of the cell. If false TAB pressing reverts to old behavior.
