Bug 82743 [Markers] improved problem filter needed (OR clauses)
when working with large workspaces I find the current problems filter not powerful enough. If I were able to AND and OR the conditions available from the UI then I would solve all my use cases. my most needed one is : I would like to see ERRORS anywhere in the workspace OR WARNINGS in the current selected project

.getSection(TAG_DIALOG_SECTION);
        if (settings == null)
            settings = workbenchSettings.addNewSection(TAG_DIALOG_SECTION);
        return settings;
    }
    protected void createActions() {
        super.createActions();
        ISelectionProvider selProvider = getSelectionProvider();
        addGlobalTaskAction = new ActionAddGlobalTask(this);
        deleteCompletedAction = new ActionDeleteCompleted(this, selProvider);
        markCompletedAction = new ActionMarkCompleted(selProvider);
        propertiesAction = new ActionTaskProperties(this, selProvider);
    }
    protected void createColumns(Table table) {
        super.createColumns(table);
        TableColumn[] columns = table.getColumns();
        if (columns != null && columns.length >= 1) {
            columns[0].setResizable(false);
            if (columns.length >= 2)
                columns[1].setResizable(false);
        }
    }
    protected void fillContextMenu(IMenuManager manager) {
        manager.add(addGlobalTaskAction);
        manager.add(new Separator());
        super.fillContextMenu(manager);
    }
    protected void fillContextMenuAdditions(IMenuManager manager) {
        manager.add(new Separator());
        manager.add(markCompletedAction);
