Currently if somebody wants to do some peer operations (for whatever reason) via the GUI, they have to select 1-by-1 and do them individually. This is just very inefficient when the same operation has to be carried out on multiple peers. It would be nice to be able to select multiple peer at once and e.g. ban them all.

{
    if(!view || !view->selectionModel())
        return QList<QModelIndex>();
    return view->selectionModel()->selectedRows(column);
}
QString getSaveFileName(QWidget *parent, const QString &caption, const QString &dir,
    const QString &filter,
    QString *selectedSuffixOut)
{
    QString selectedFilter;
    QString myDir;
    if(dir.isEmpty()) 
    {
#if QT_VERSION < 0x050000
        myDir = QDesktopServices::storageLocation(QDesktopServices::DocumentsLocation);
#else
        myDir = QStandardPaths::writableLocation(QStandardPaths::DocumentsLocation);
#endif
    }
    else
    {
        myDir = dir;
