We just released a new version of InboxRuler. The last version (1.44) unfortunately contained a serious bug which prevented users to save new or modified rules. This release not only fixes this issue but also has additional possibilities to select messages based on date. It is now possible to select messages by for instance a week ago, a month ago and so on. This can be handy if you want to clean up your inbox to move all e-mails older than 3 months to an archive folder.
As always, please let us know if you have suggestions for new functionality or what can be improved in InboxRuler!
