Murcielago I wanted to ask [...] if there is any news or a (very) rough timeline regarding this killer feature.
I think it is rare for any kind of pre-announcement/timeline/... to be made more than a month or two before a feature ships.
There is an issue on the tracker (#2197), and it's possible to subscribe to the issue to receive mail when the tracker entry changes. The developers have requested that people do not add "I want this too!" comments to issues -- doing this will result in the comments being deleted and the developers feeling grumpy toward the commenters (and, who knows, maybe feeling grumpy about working on the issue). It is fine to use the reaction-emoji feature on the topmost comment.
