The toolbar used in the Activities has been redesigned. The previous design using small text tabs to group toolbar options together caused a number of usability difficulties. Many of these issues have been addressed in the redesign. For example, the redesign provides a solution for the "how do I stop an activity" issue, pointed out in {{Bug|452}} (the older toolbar design did not provide an always visible "Stop" button, causing confusion for our young learners). Among the Activities, Browse, Write, Calculate, Terminal, Read, ImageViewer, and Turtle Art have already been ported to use the new Toolbar design, while work on many others is under way. See [[Features/New Toolbar Design]] for more details about the new design.

=== Switch to Metacity window manager ===

=== Switch to Metacity window manager ===

Sugar has [[Features/Metacity|switched]] from Matchbox to a new window manager, [http://en.wikipedia.org/wiki/Metacity Metacity]. Matchbox was designed for small devices; it forces ''all'' applications to run maximized. Sugar can be run on devices with much larger screens, and while activities native to Sugar are designed to be run maximized (full screen), some applications not specifically designed for Sugar can behave in unexpected ways when run with Matchbox. The switch to Metacity means that many "unsugarized" applications will run better inside of Sugar (e.g. Inkscape, Gimp). We endeavour to ensure that "traditional" desktop applications run well in Sugar, without requiring programming or behavioural changes.

=== Ad hoc Networking ===

New ad-hoc networking facilities allows you to connect with other Sugar users over wireless in an ad-hoc manner without relying on any wireless networking infrastructure. This is the so called "under-a-tree scenario", where children can work, play, and learn collaboratively in any place imaginable, without requiring any wireless access point, which for many children is unavailable or only available at school. (The One Laptop per Child XO-1 computer provides similar functionality with its firmware-based 802.11s (mesh) network.)[[Features/Ad_hoc_Networking | Ad-hoc networking]] allows Sugar to use this feature with most of the wireless hardware commonly found on computers. Furthermore it allows one to share an Internet connection using the same mechanism. Fore more details see [[Features/Ad_hoc_Networking/Testing|Ad-hoc network testing]].

=== Widgets ===

=== Widgets ===

* '''New Toolbars:''' Sugar has switched to a new toolbar design. The simplest example can be found in the [http://git.sugarlabs.org/projects/hello-world/repos/mainline/blobs/master/activity.py#line44 hello world] activity. If you want to group functionality into a secondary toolbar you can have a look at the [http://git.sugarlabs.org/projects/terminal/repos/mainline/blobs/master/terminal.py terminal activity]. To have a consistent layout over activities please group the edit and view toolbar to the left. The items on the toolbar should be left centered.

* '''New Share button''': If your activity does not support collaboration you can set the activity class member max_participants to '1' which makes the share button insensitive.

* '''New Share button''': The design of the share button has changed ([[0.86/Notes#New_share_button]]). If your activity does not support collaboration you can set the activity class member max_participants to '1' which makes the share button insensitive.

* '''PaletteWindow''': A PaletteWindow widget has been added.

* ''TBA''

* To add the toolbar_box to the activity we use a toolbar_box property now instead of the set_toolbox method.

* ''TBA''

* Switch from [http://en.wikipedia.org/wiki/Matchbox_%28window_manager%29 Matchbox] to [http://en.wikipedia.org/wiki/Metacity Metacity]. To activity authors this means that their windows need to be user-resizable which in turn requires that the layout adapts changes in window size.

* Sugar: [[Features/Metacity | '''Metacity:''']] The switch to [http://en.wikipedia.org/wiki/Metacity Metacity] as window manager is dependent on this [http://git.gnome.org/cgit/metacity/commit/?id=b625ec30d99b2dcf86d8fa78b09f6d04dce3a6e0 commit] that adds a command line option to disable autofullscreening maximized windows without decorations.
