Improving support for OS X 10.9 Mavericks, Ergonis Software has released PopChar X 6.4 with an improved “corner P” that appears on the active screen on all monitors in a multi-monitor configuration and fixes several other display issues with Mavericks. The font discovery utility also improves its responsiveness in several areas, with the update quickening the pace of displaying the character table, improving the speed of detecting the font in the current application, reducing background activity by reloading available fonts only when necessary, and remembering the previously selected font separately for each application.

In Snow Leopard, Option-clicking the Volume icon in the menu bar displays a list of sound input and output devices. Choose one to switch to it; it's much easier than using the Sound preference pane. Also, hold Shift and click the icon to set the system volume, which is separate from the general output volume.
