Delete all offers
I would like to delete all "Offers". The UI is really weird for this. If you select "All", then you are no longer targeting offers. With the new UI, you have to select at least one message on the "Offers" tab, then you can select "All" messages, but it's limited to just the 100 messages in your current list. I would like to nuke them all, from all time, similar to how Delete all Spam was on the old UI.
What's even more troubling is that I can select the Offer messages and delete them 100 at a time, but then the Delete message response has said 200, or 300 messages were delete. So, how many messages were actually deleted? And, which ones? You guys might want to roll the new UI back until you fix this bug. Losing important messages would be very bad.

What is more useful is to bring back the select all button and delete selected. That function is very useful and a lot of people uses it.
