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

IDialogSettings settings = workbenchSettings
                .getSection(TAG_DIALOG_SECTION);
        if (settings == null)
            settings = workbenchSettings.addNewSection(TAG_DIALOG_SECTION);
        return settings;
    }
    protected void createActions() {
        super.createActions();
        propertiesAction = new ActionProblemProperties(this,
                getSelectionProvider());
        resolveMarkerAction = new ActionResolveMarker(this,
                getSelectionProvider());
    }
    protected void createColumns(Table table) {
        super.createColumns(table);
        TableColumn[] columns = table.getColumns();
        if (columns != null && columns.length >= 1)
            columns[0].setResizable(false);
    }
    protected void fillContextMenuAdditions(IMenuManager manager) {
        manager.add(new Separator());
        manager.add(resolveMarkerAction);
    }
    protected DialogMarkerFilter getFiltersDialog() {
        return new DialogProblemFilter(getViewer().getControl().getShell(),
                problemFilter);
    }
    protected IField[] getHiddenFields() {
        return HIDDEN_FIELDS;
