Tags
Version 1.2 of reportbug-ng now shows the tags of a bug if available. This was long overdue. Now you can for example, quickly search your bugs for the ones with the moreinfo-tag set and sort the resulting list by the date of the last action. This should give you a quick overview of bugs which may need some action (eg. another reminder to the submitter) or can potentially be safely closed.
In the next step I’ll improve the filter of rng and add a context menu which will allow to manipulate the tags of one or more bugreports and send all the changes in a single mail to control@bugs.debian.org.
