Well iPad and iPhone don't have that feature and no-one posting here will ever know if it's coming. If Amazon ever does add it, the first everyone will know about it is when the updated app is released.
You seem to think they are just sitting around waiting for you to contact them and will add this feature immediately.
Strange as it seems, Amazon likely has a development strategy mapped out for years ahead and may or may not adapt suggestions from outside in nay given time frame.
There are things many people have been asking for since Kindles began that have yet to emerge. So be patient and do not assume your one request is going to sway an enormous company into making changes you want.
Here is what Amazon itself says about this:
"Although we would like to enthusiastically embrace every idea proposed to us, regretfully, our investment strategy and internal objectives do not allow us to do so. "
NOTE: I do NOT speak for or represent Amazon in any fashion. This is a customer to customer forum.
