The RichText in-place editor only expands when the user moves to another node. When the user types into the control, the lines scroll out of view. This is difficult to use when the control is only one line deep (as an empty node would start as).
Proposed Solution:
What is needed is an event or option that will allow the column to vertically expand when word-wrap occurs in the RichText editor, so that all of the text is always visible.

We have implemented the functionality described in this ticket. It will be included in our next update(s).
Please check back and leave a comment to this response to let us know whether or not this solution addresses your concerns.
Additional information:
With VCL 13.1, you can specify the manner in which an in-place multi-line editor is sized when an end-user types in it. To accomplish this, use a tree list's OptionsBehavior.EditAutoHeight property or a column's Options.EditAutoHeight property. The property values include:
- eahNone. An in-place editor is displayed as a single-line scrollable text field.
- eahEditor - In-place editor sizing. In the edited cell, an in-place editor is sized vertically to fit the content entered. When an end-user has finished editing, the height of the containing node is automatically changed to fit the new data. You can emphasize the border of the editor displayed in this mode via a tree list's OptionsView.EditAutoHeightBorderColor property.
- eahRow. Node sizing. The entire node being edited is dynamically sized when wrapping to the next line within an in-place editor. This option is in effect if a tree list's OptionsView.CellAutoHeight property is set to True.
A tree list's EditAutoHeight property is overridden by a column's Options.EditAutoHeight property.
Run the ColumnsMultiEditorsDemo shipped with the ExpressQuantumTreeList Suite and type into the Memo Editor to see the new functionality in action.
