Edit TestPeakPickingTutorial and turn on PauseForScreenshots.
Run the test until you see a trained Edit Peak Scoring Model.
Click on the headers in the score calculator grid.

Result: Sorting messes up the correlation between formatting, enabling, etc. This grid just can't deal with sorting at the moment, but it is perfectly reasonable to want to be able to sort by contribution.

Thought maybe you could fix this one easily, Nick.

Can you fix this?
You can get to the EditPeakScoringDlg by going to:
Edit > Refine > Reintegrate
and choosing "Add".

It looks like what we need to do is handle the "ListChanged" event on "bindingPeakCalculators". In that event handler we should call "UpdateCalculatorGrid".
Also, UpdateCalculatorGrid needs to be changed. Currently it looks at "_peakScoringModel.Paramters.Weights[rowIndex]" which is not the right thing to look at once the grid is being sorted.
Instead, it should look at "PeakCalculatorWeights[rowIndex]".

This got fixed a while ago.
