If you want to document Blender 2.5 features please edit pages under Doc:2.5/Manual.
If a "2.5" page doesn't exist please copy the text from 2.4x Manual and edit the new page (i.e. you should paste the wikitext from this 2.4x page to this new 2.5x page and then update the latter with 2.5 features)
[edit] Panels
Panels generally appear in the Buttons window and by default the Buttons window is at the bottom; see (Buttons window). The Buttons window includes the Button window header and panels.
Each button on the Buttons header groups panels together into what is called a Context. And those Contexts are grouped further into Sub-Contexts. For example, all Material panels are grouped under the Shading context and Material sub-context.
The panels are not fixed in position relative to the window. They can be moved around the window by LMB 
clicking and dragging on the respective panel header.
Panels can be aligned by RMB 
on the Buttons Window and choosing the desired layout from the Menu which appears (Button Window Menu.). Using Wheel 
scrolls the Panels in their aligned direction and CtrlWheel and CtrlMMB 
zooms the Panels in and out. Single Panels can be collapsed/expanded by LMB clicking the triangle on the left side of their header.
Particularly complex Panels are organized in Tabs. Clicking LMB on a Tab in the Panel header changes the buttons shown in (Panel with Tabs Example.). Tabs can be "torn out" of a Panel to form independent panels by clicking LMB on their header and dragging them out. In a similar way separate Panels can be turned into a single Panel with Tabs by dropping one Panel's header into another.
Note : The colors of the other Panel's borders change (to white by default) when you can release the mouse button to create a tab from the selected Panel. Example
For further details about each panel see the Reference panels section.
