+	* GstInspector/GUI.py (FilterManager.__init__)
+	(FilterManager.handle_filter_combo_changed)
+	(FilterManager.handle_ui_filter_param_changed)
+	(FilterManager.clear, FilterManager.handle_load_finished): Ignore
+	filter parameter changes during load.  This makes disabling of
+	filtering during reload work properly, resulting in 30% time
+	savings when reloading data with a filter enabled.

 	* GstInspector/GUI.py (ColumnManager.detach)
 	(ColumnManager.activate_sort): When detaching while sorting is
 	deactivated, save the stored default sort options instead of the values
