Sometimes it would be very helpful to have a possibility to add a custom column by plugin like the advanced setting for custom columns. I would like to add a column conditionally, e.g. if the repository XY is used in the build (configuration) it should show a column which is displaying the revision/head committer/etc.

in ConfigurationOverview there might be something like

for (BuildColumnContribution col : contributions) {
  if (col.shouldShow()) {
    columns.add(new Column(col.getName(), col.getValue(build))
  }
}

or so... Mind this is just a pseudocode example.

Of course there are more thing to think of, but just that would be great.
