Component refactoring about twincolgridaddon

[mlopezFC]

Good point.

The following things pops into my mind. Maybe we should consider that this component was meant to be a better replacement of List Builder, giving the features of dealing with the cases were more data is needed for displaying a lot of items (columns, filtering, sorting, etc.). Taking that into account, now I think that giving the possibility of customizing each of the grids individually goes beyond the idea of the original use case, because if you want to move around data from two different looking grids is maybe another different component.

Thinking in that direction, those methods that we added to configure the styles of each grid, could have been 3 instead of 6, and simply to add a suffix for each of the class names of the internal grids ("-left" and " -right ") would do the trick with a smaller API.

So basically I think that giving the possibility of customizing each of the grids should be something achievable only by extending the component, but the API should remain clean for the original purpose of the component (basically almost every customization should apply to each of the grids at the same time).

Back to triage.

I disagree. There is and/or there should be public API for customizing the component.

Unassigning myself because this issue still needs triage.
