Add an auto-redraw option.
Currently, ParaView automatically re-renders the screen after any filters have been applied, which can cause large delays if datasets are large and representations are set to anything but outline. It would be nice to have an auto-redraw tickbox option with a redraw(render) button on the UI, so that the user can apply any filters and render whenever they want manually by button clicks. A similar effect can be achieved using representations, but the drop-down box can prove fiddly if it has to be changed frequently.

The easiest way to do that is to open a spreadsheet view. This way, even when you create a new filter, no geometric view will be computed.
