[QGIS-Developer] Disable/commenting provider filter?

[Matthias Kuhn]

Hi Richard,

An enable/disable checkbox that works without deleting the filter would be
very nice. Just like data defined symbology where you can disable it
without losing the expression.

Short term workaround for you:

  TRUE /* [yourfilter here] */
