Hard to believe this forum does not have a sort or filter function.

Hard to believe the issue needs to be forwarded to the product manager.

Hard to believe that imediately I get a reply (which promises zero improvements) that I and others are cust off form commenting.

No doubt this thread will also be blocked!!
