Please change the filter on the node management page to require clicking a new 'Apply' button after setting/clearing filter conditions.
I very often set 2 or 3 filter conditions when browsing the node management list. For each condition changed, page resubmits the query and then refreshes the contents of the page. This is nice when changing only one condition, but is a major annoyance when changing more than 1. At the same time, having static condition selection that is submitted with an 'Apply' button would also reduce the number of queries run on the SQL Server, offering small opportunities for better overall performance of the application.
