What new apps should I build for the ADSK Portathon?

Autodesk is generously offering me (and everyone else) $100 each for submitting up to 5 new apps to http://apps.exchange.autodesk.com/en.

So friends, what new apps should I create?

P.S. The apps need to be submitted to Autodesk by September 14, so small/medium sized utilities will be a better fit than big projects like an FBX Importer

Set graphic overrides for an element in a view

2014 includes a new View.SetElementOverrides that can be used to set view-specific graphic overrides for a specific element.

public void ElementOverride()
    Document doc = this.ActiveUIDocument.Document;
    UIDocument uidoc = this.ActiveUIDocument;
    ElementId id = uidoc.Selection.PickObject(ObjectType.Element,"Select an element").ElementId;
    OverrideGraphicSettings ogs = new OverrideGraphicSettings();
    ogs.SetProjectionLineColor(new Color(0,255,0));
    using (Transaction t = new Transaction(doc,"Set Element Override"))
        doc.ActiveView.SetElementOverrides(id, ogs);

Click twice to create a cropped dependent view

Here is how  to prompt the user to click twice and use those points to create a new dependent view cropped to the rectangle formed by those points.

public void MakeViewAndSheetWith2Clicks()
    Document doc = this.ActiveUIDocument.Document;
    UIDocument uidoc = new UIDocument(doc);

    // prompt user to pick two points
    XYZ lowLeftPickPoint = uidoc.Selection.PickPoint("Pick lower left corner");
    XYZ upRightPickPoint = uidoc.Selection.PickPoint("Pick upper right corner");

    // create a new BoundingBoxXYZ & set its Min and Max to the XYZ points selected by the user
    BoundingBoxXYZ bboxFromPicks = new BoundingBoxXYZ();
    bboxFromPicks.Min = lowLeftPickPoint;
    bboxFromPicks.Max = upRightPickPoint;

    // Find a titleblock in the project, or use InvalidElementId to create a sheet with no titleblock
    ElementId titleblockId = ElementId.InvalidElementId;
    FamilySymbol titleBlockSymbol = doc.TitleBlocks.Cast<FamilySymbol>().FirstOrDefault();
    if (titleBlockSymbol != null)
        titleblockId = titleBlockSymbol.Id;

    ViewSheet sheet = null;
    using (Transaction t = new Transaction(doc,"crop"))

        // duplicate the active view
        ElementId newViewId = doc.ActiveView.Duplicate(ViewDuplicateOption.AsDependent);
        View newView = doc.GetElement(newViewId) as View;

        // set the crop box of the new view to the bounding box created from the two picked points
        newView.CropBox = bboxFromPicks;

        // Create the new sheet
        sheet = ViewSheet.Create(doc, titleblockId);

        newView.Name = sheet.Name + "-" + sheet.SheetNumber;
        newView.Scale = 10;

        // Create the viewport to put the new view on the new sheet at (0,0,0)
        Viewport.Create(doc, sheet.Id, newViewId, XYZ.Zero);
    // make the new sheet the active view
    uidoc.ActiveView = sheet;

Create a View/Sheet Set

public void CreateSheetSet()
    Document doc = this.ActiveUIDocument.Document;

    // create a new ViewSet - add views to it that match the desired criteria
    ViewSet myViewSet = new ViewSet();
    string match = "S";
    foreach (ViewSheet vs in new FilteredElementCollector(doc).OfClass(typeof(ViewSheet)).Cast<ViewSheet>()
             .Where(q => q.SheetNumber.Contains(match)))

    // get the PrintManger from the current document
    PrintManager printManager = doc.PrintManager;

    // set this PrintManager to use the "Selected Views/Sheets" option
    printManager.PrintRange = PrintRange.Select;

    // get the ViewSheetSetting which manages the view/sheet set information of current document
    ViewSheetSetting viewSheetSetting = printManager.ViewSheetSetting;

    // set the views in this ViewSheetSetting to the newly created ViewSet
    viewSheetSetting.CurrentViewSheetSet.Views = myViewSet;

    if (myViewSet.Size == 0)
        TaskDialog.Show("Error", "No sheet numbers contain '" + match + "'.");

    using (Transaction t = new Transaction(doc,"Create ViewSet"))
        string setName = "'" + match +"' Sheets";
            // Save the current view sheet set to another view/sheet set with the specified name.
        // handle the exception that will occur if there is already a view/sheet set with this name
        catch (Autodesk.Revit.Exceptions.InvalidOperationException)
            TaskDialog.Show("Error", setName + " is already in use");
    TaskDialog.Show("View Set", myViewSet.Size + " sheets added to set");
