This topic has been discussed before, but, for whatever reason, that discussion is frozen.
When using the metric widget in a sight every selected cell will get the name of the column it's in as a passenger. While I can't find any reasons for this approach, it would be nice to have an on/off switch. I know one can remove the column name from a sight on a case by case basis, but it becomes a pain when the number of selected cells is large.
