Support the nesting of a RadDocking control in RadPane or other RadDocking control.

Available in the 2016 R3 Release.

Please take a look at our help article for more information:
http://docs.telerik.com/devtools/wpf/controls/radpasswordbox/overview

Add new control to the suite: Wizard control.

We would like to have the ability to merge cells vertically with same content. Consider to do the same horizontally.

Add SelectedItemsSource property which can be bound to a collection in the view model. In this case when the RadListBox is in Multiple/Extender mode, the selection can be manipulate from the ViewModel.

Allow developers to add their own functions to the list of available functions in the RadExpressionEditor and then pass these functions to the LINQ runtime when the expression tree is built. Add support for custom Categories as well.

Scheduled for: 
The feature will be available in R1 2019, scheduled for the mid of January 2019. 

Add new control to the suite: TimeSpan Picker

Implement support for content controls (a.k.a. Structured document tags), which will allow inserting editing controls in the document:

- Rich Text
- Plain Text
- Check Box
- Combo Box
- Drop-down list
- Date picker

Do not confuse this feature with form fields support (see http://feedback.telerik.com/Project/143/Feedback/Details/146869 ).

In the following scenario:

    Floating Pane's size has been changed.
    The layout has been saved.
    The layout has been loaded.
    The Pane has been docked.
    Making the Pane floating should retain the custom size from point 1.

Ability to grouped the appointments in hierarchical groups.

Implement DragAndDrop in terms of allowing a reordering of the ToolBars in the ToolBarTray and moving toolbars from one tray to another.

Is there a way to get the map to continuously scroll without seeing the gray area? As an example, GoogleMaps, MapQuest, etc.. let you scroll left to right without getting to the "end of the world", it just continues to wrap around. I'm trying to avoid seeing the gray when I scroll too far left or right.

The feature for WPF will be available with R3 2016 in September.

Add support for shapes, and especially for shapes with textual content. 
In OOXML, shapes are represented by the wps:wsp element, and shapes with textual content by <wps:txbx>, <w:txbxContent>.
Such shape can be added to a Word document using the Insert -> Text -> Text Box -> Draw Text Box, or through a shape's context menu -> Add Text.

Note: Do not confuse with Text/Rich Text content controls (https://feedback.telerik.com/Project/143/Feedback/Details/113730 ).

Would it be possible to add a new theme that accurately tracks the Google Material Design guidelines?  (http://www.google.com/design/spec/material-design/introduction.html).

Available in the 2017 R2 Release.

Implement import of documents containing Type 3 fonts.

You should be able to prevent the horizontal/vertical overlapping of routed connections . This way the connections should be easier to differentiate.

To better differentiate connections, users might:

            --- use labels on the connections

            --- use bezier connections

            --- use different colors for different connections

            --- use more custom connectors and attach the connections to not used connectors

            -- use AStartRouter instead of the default one (Grid Router)

Coming from RadControls for WinForms I did miss this control.
It didn't take me long to create my own alert controls, but it would be nicer to have them styled and behave like all other telerik controls.

Allow restored tiles to span multiple columns/rows. This feature is somewhat similar to allowing custom sizes of restored tiles.

We have create an SDK example showing how the default panel of the RadTileView can be modified to achieve this scenario: you can find the demo in our online git hub repository (https://github.com/telerik/xaml-sdk/tree/master/TileView/RestoredTilesToSpanMultipleRowsAndColumns).

A useful new control would be : RadWebcam

It would show webcam view in realtime and call a function each x seconds (or ms), would be useful for :
 - user picture to attach to its user account
 - quick product picture
 - and for my need : call an external function for barcode recognization

I think it would be easy and fast to create this control for WPF, and it would fit perfectly with Silverlight 4 (or 5 ?) webcam support.

Add built-in support for smart series item labels i.e. automatic label arrangment that ensures the labels do not overlap.
