Selective display of categorised layer

[mesajs]

When symbology for a vector layer is set to 'Unique value', could a check box be added beside each classification in the legend to turn on/off rendering of classifications (and associated labels).

Eg If a classification field has values 'Small', 'Medium' and 'Large', the user could uncheck 'Small' and only 'Medium' and 'Large' objects would be displayed.

Ideally, only the selected classifications would appear in map legends on Map Composer and Quick Print.

But there is a "delete classes" button, isn't that enough?

Delete classes certainly stops a class displaying, but displaying it again requires setting up the symbology for that class all over again. This can be a problem for less sophisticated users.

I was thinking of making it as easy as turning whole layers on and off.
