It would be cool to be able to change the order of Replicator items, for example to change the filter or generator ordering. This is tedious to do by hand, but it is also a little tedious in the code because we need to delete and rename keys in the INI on the file system. The INIParser should be well tested before implementing this, but then I think it should be done.
We could try to implement custom dragging for the Groups (https://doc.qt.io/qt-5/dnd.html), but I don't know it's worth it since then we would have quite a way to drag always. Simpler would be to expand a list that can be re-arranged with an underlying model of the items. Quick & dirty would be to query two indices and swap.
If we have it, we would enable it in the Selector also for ordering e. g. %COPY.
