Any chance of bundling?

[jcgoble3]

The major critical feature from Inbox that is missing in Gmail for me is bundling by label. I don't mean the default inbox categories (Social, Promotions, etc.); I mean the ability to tell it "I want all emails with this arbitrary label that are in my inbox to be collapsed into one line that I can click on to expand the list". My inbox is completely unmanageable without these bundles.

Is there any chance of getting this feature? I would not mind at all having to dig into a separate extension settings screen to manually type in and manage which labels I want bundled if that's what it takes. This is literally the make-or-break feature of Inbox for me, and the reason I am postponing Windows updates because I refuse to close my Inbox tab until I am forced to. I use Firefox, if that matters.
