The very recent of gmail categories is great.
Some emails are half-spam. You register in a site (e.g. amazon) for doing some shopping and then they keep sending info. Or Tech news site.
On a daily basis I don't have the time to read the newsletters and daily deleting the emails is a waste of time. But they aren't 100% spam so I don't want to block their emails forever.
If we could mimic the right button option where you say to which folder we want to move the email and if we want to create a filter to do that automaticcaly ti would be great.
Creating those special 5 categoriy folders (promotions, social, etc) is a plus, since I don't want to have to select manually among more then 200 folders in MDaemon.
