The feature needs to cover functionality as follows: The logarithmic axis has an exponent step (1, 10, 100, 1000) and the current ticks support of the axis only plots evenly distributed ticks. Clients, however, sometimes need to display unevenly distributed ticks (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and so on).

The GridViewCheckBox cell calls the license verify method in its constructor. This potentially could lead to performance degradation when the RadGridView is populated with a large number of cells. Each scrolling operation will trigger the GridViewCheckBox creation thus licensing validation.

The text content control (SDT form) cannot be edited when the Lock property of the associated SdtProperties is set to SdtLocked. The SdtLocked setting should prevent deletion of the form only, but the user should be able to still edit the text. 
The issue reproduces only if the content control was locked before any text is entered (when the text placeholder is displayed).

Add protection mode that allows to make the document readonly, but allow forms editing. In MS Word this can be enabled via the "Restrict Editing" menu. The option is called "Filling in forms" and protects the document, but leaves the Sdt elements (the forms) editable.

It seems that the System.Net.Http package dependency was added because it was required by SharpDX which was used by RadWebCam in older versions of Telerik. After the migration to SkiaSharp the package dependency was no longer needed, but it seems it wasn't removed.

Remove the System.Net.Http package dependency.

Currently, when you insert a content control using TextProperties, CheckBoxProperties, etc., the applied font is the default one for the content controls. Instead, it should use the font of the associated span/paragraph where it was inserted. For example, if you type "Hello world" and set its font size to 36, then place the cursor between "Hello" and "world" and insert a textbox content control there, the font size of the textbox will be something like 10, instead of 36.

Synchronize the font properties and make sure that the content control uses same font as the existing paragraph/span.

Currently, the appointments in the same group in TimelineViewDefinition will be drawn on multiple lines if their date ranges overlap. Internally, the group height is split into "rows" for each overlapping that happens and then each appointment is rendered on the corresponding row.

Add a mechanism to control the number of rows and the row position of each appointments in the same group.
