Newly released GNOME 3.10 desktop has quite a handful of great new features, but what's especially interesting is the much improved Wacom applet.

The majority of the work was done by Joachim Rocha who joined Red Hat shortly before the new development cycle. Among the first things that Joachim did was the rewriting of calibration. Here's how it works now:

The next thing he did was reimplementing the mapping of ExpressKeys and touch rings to various actions. Jakub Steiner designed a whole new UI for that, although it seems to heavily borrow from Wacom's own new configuration app that you get with Intuos 5 and newer models of Cintiq.

If there's no on-screen display layout for your Wacom device, you still get the feature via a dialog, where you can map a button to four types of actions:

sending a keystroke;

sending a modifier;

showing onscreen help;

switching monitor.

That isn't all: the Wacom applet also got support for OLED in Intuos 4 (a feature added by Przemo Firszt). If you mapped your ExpressKeys to e.g. some hotkeys, OLEDs will display those hotkeys.

It's not quite clear, whether the Wacom applet also supports displaying OSD key mapping messages when you hover your finger over ExpressKeys in Intuos 5. Do tell us what you discover.

As for the other "graphics" applet in GNOME, the GNOME Color Manager, it didn't really get any changes except bugfixes. However now that basic Wayland support is available in GNOME, and Wayland itself supports CMS, Richard Hughes is finally going to work on fullscreen color management in GNOME. His GSoC student who was supposed to write the shader code for that unfortunatey failed the final evaluation.
