Ergonis Software has released PopChar X 6.5 with a new custom insertion technique, which should make it faster to insert characters in applications that don’t reliably support direct event-based insertion of characters. The update also provides a workaround for a problem that caused the search field to be cleared while entering search terms on OS X 10.9 Mavericks, squashes a bug on non-English systems that prevented PopChar from remembering the previously selected layout, and improves the speed of clipboard-based insertions for many applications.

Compare More Easily in Apple Mail
In Apple Mail, if you need to work back and forth between two different views of Mail's mailbox contents, you can do so quite easily. For example, you might want to look at a mailbox holding all filtered-in sales orders from the past week while also looking at a smart mailbox showing unanswered customer questions.
To avoid constantly clicking between mailbox views and losing your context each time, choose File > New Viewer window to get a second window and then arrange each window as desired.
