Usually name of variables / metrics / segments, but also their value, are something really technical.
That kind of values absolutely do not suit the needs of top management who cannot read technical description.
Also, when we do complex workspace the name of column is hidden because no space available in layout.
So, why dont allow to overwrite and change color of any string we have into column/row head or cell?
Great suggestion - we are actively working on ways to mitigate this. One feature that we are releasing soon is the ability to rename labels within visualizations.
