Feature request: Unified labels
I would appreciate 'unified labels' (or unified folders), in addition to unified inboxes. Airmail already has the foundation for this. More specifically, we just need to be able to customize the current 'To Do/Done/Memo/etc' with the ability to add/delete/rename our own custom labels. Our email account specific labels or folders can be mapped to these unified custom labels. Boxer Pro (iOS) does this and it has changed my workflow permanently.
I too really really want this. Its very difficult to use the label system for me personally without it being unified as I will get emails relating to a work project in both a work and personal email address.
+1. I use a workaround by creating smart folders with search criteria "label:MY_LABEL" .. This works fine, however, I have to manually create smart folder for each label. An integrated unified label system would be a plus plus point.
