Advertisement: Are you tired of loosing your selection in the message list when a filter moves a mail from your inbox to its final destination? Are you getting blind due to the favorite folders list flickering when a bulk of emails are moved around? Are you seeing strange crashes and kmail getting unresponsive when you move a big chunk of emails from one folder to another? Then this patch is made for you! Further explanations: Don't use the itemMoved() signals in the ETM for items anymore. It is the right solution long term, but short term it is not usable if all the proxy models around the ETM don't support the feature properly. Right now most (if not all) of our proxy models transform itemMoved() signals into layoutChanged() signals, and for instance when that reaches the message list it simply resets the whole message list model. Such a reset then happen for each of the item moved, potentially flooding the system with computations for threading, but also generating flickers in the favorite folders list or loosing the selection for the less dramatic cases. Downside: Because of the move speed up, you actually see the changes now, so the mails progressively disappearing from the source collection to appear in the destination collection. For this to disappear we need to compress the changes in bulks, which is ongoing work. But at least now it's faster and more usable.
