Ability to merge similar threads into a single thread. :)
I would say it would be great to group threads. For example, we get messages from different people with different subject lines, which all belong to a single project. It would be great if we could group them, so that they could be accessed from one place.
@Svetlana Malakhova: You can achieve this by referencing other conversations in a conversation. See in this screenshot we have a label named *Features: requested* in which we created one conversation for each feature request we received. Inside this conversation, we link to all conversations relevant to the feature (e.g. user email asking for it).
You can drag and drop conversation in any other conversation, or right-click on their preview of a conversation and click *copy link*, then paste this link in any conversation comment box.
@Philippe Lehoux: Hi Philippe, thank you very much!
