Feature description

It would be great to be able to get all the unsaved data (current_value/current_parent_value or something like that) from parent features in child features. In my case for example I would like to estimate the "geometry-length" of the unsaved line.

You may think of a simple example: You are digitizing a line (parent feature), which represents a route, where some different types of work (child features) have to be done in different withs later outside in the field. To estimate the amount of work already during digitizing, it would be great to show the line length of parent-feature as a (editable) default value already when digitizing the child features in the same step while digitzing a parent feature.

It would be great if there will be no need to save the parent feature first - which costs extra steps / efforts to save/identify the line features.
(In my case during collection of child-data I may change the default-value because different types of work, which have do be done may be done in different withs (and quantities))
