Describe the solution you'd like

From @svavoi, to be discussed with the PSC

• Display which layers are used to be snapped on and let the user select/unselect them
• Display which fields are mandatory
• Indicate which field causes a constraint error (or any kind of server error)
• Dropdowns with autocompletion
• It would be nice to be able to set attributes read-only for the right panel. For example, for attributes that are calculated by a trigger. This value should be greyed out.
• Drawing of multipolygons/multipoints/multiline, could be an additional action like “cut geometry”
• Drawing of an arc or a circle
• Possibility to show area size when you draw a feature
• Possibility to draw a line or a polygon of a specific size
• Possibility to draw rectangular angles (or user-defined angles)
• Possibility to set a point to a specific coordinate
• Copy attributes form another geometry
• Copy a geometry from a different (not editable) layer. Maybe they could be configured like snapping layers?
• We have editing layers that hold many attributes (>10 attributes), it would be good to have a possibility to open another window with an additional form (for example an external plugin) to set the non-geometry attributes

Some of the features are already available in version 2.4 or 2.6 (read-only attributes, mandatory fields, constraint errors). At the moment we don't need more editing improvements. I close this ticket.
