Webin has released ReadKit 2.3.2, a small maintenance update to the RSS client and read-later app that nonetheless eases a few specific frustrations. The new version fixes sync problems with Feedly, an issue with the built-in browser collapsing when items were marked as read, the storing state of the “Is shared” checkbox on the Pinboard sharing panel, and minor issues with OPML importing.

Fun Way to Send Attachments in Mail
If you're working in a file that you want to attach to a message in Apple Mail, you can transfer the file to Mail easily: From the title bar of the file's window, drag the little proxy icon to Mail's icon on the Dock. Your Mac will make Mail the active application and open a new outgoing message, with the file attached.
(If your icon won't drag, the file probably isn't saved.)
