Add a CloseButtonPosition state like the InPane one but only for the active (selected) Pane

As a developer using the RadDocking control, I want to be able to make the Popups of the AutoHideAreas non-transparent without overriding the whole theme.

Place a notepad over the MainWindow and mouseover an unpinned pane - the autohide area shouldn't show up.

Pinning a pane instance will cause that instance's tab to go to the first place of the group in which it is in the DocumetnHost of the control. This behavior could be observed in MS Visual Studio 2013

Currently the arrow buttons appear only when the TabStripPlacement is set to top.

Reorder a pane and save the layout. Reorder another pane and load the layout - the wrong pane is selected.

When using Implicit Styles setting the DropDownDisplayMode of a PaneGroup to Visible in the Office themes causes the DropDownButton to be invisible.

Make it possible to float unpinned Pane by dragging them from the AutoHideArea.

Make it possible to dock panes inside and outside of the DocumetnHost via it's compasses

If there are more than 2 Panes in an PaneGroup closing one of the Panes with index bigger than 1 calls ActivePaneChanged  event twice.

When the Dock's auto-hide area is is about to be shown on two monitors simultaneously it is shown only on one of the monitors.

After upgrading to Telerik WPF 2019.1.116 from 2018.3.1010 we receive a lot of:

System.ComponentModel.Win32Exception (0x80004005): Invalid window handle
   MS.Win32.UnsafeNativeMethods.GetWindowText(HandleRef hWnd, StringBuilder lpString, Int32 nMaxCount)

Exceptions. It makes out application very slow.

In version 2018 everyting was OK. See attached scerenshots.

Currently, unpinned panes need to first be pinned in order to be floated. Floating of unpinned panes should be made possible.

As a <role> I want <ability> so that <benefit>.

AutoHideArea is opening when pin/unpin another Pane

Add better layout-related events for the Docking control like PreviewPaneStateChanged and improved the arguments of the PaneStateChanged event. Also add events for resizing of a SplitContainer, moving a ToolWindow, etc.

Add overloads for LoadLayout and SaveLayout methods of the Docking control with parameter of type XElement instead of Stream. Change the Save/Load layout code to use LinqToXML instead of XmlReader and XmlWriter.
