[Qgis-developer] Field mapper when pasting features

[Arnaud Morvan]

Hello QGIS devs,

I want to add a field mapper dialog when pasting features to layers.

For now when pasting features with attributes names that do not exists 
on the destination layer,
those attributes values are lost.

When clipboard fields and destination layer fields are not strictly the 
sames,
In QGIS 3.0, I want to popup a new dialog with fields mapper configurator.

Dialog UI could be similar to Refactor Fields Algorithm, showing a list 
of destination fields :

     source expression (expression widgets) => destination field

For example, I often use this workflow :
     Open a shapefile or autocad file.
     Use the refactor fields to get temporary layer with same fields as 
destination.
     Paste to postgis database layer.

I think having this dialog showing up when needed could really ease data 
manipulation from one layer to another.
And I want to give the possibility to use expressions.

Any remarks, do you think I need to open to open a QEP for that ?

Regards
