The algorithm just allows to "override" the datasource from layers in that project. The rationale is that the project may contain relatively complex logic (atlas configuration, table joins, etc...), and that this way, everything would (hopefully) continue to work if it worked in the initial project.

With "lock layers" and "lock styles", we could at least use some predefined layers, but then it's much less practical to work with and still isn't as flexible as using a whole project.

Great work!

I've uploaded my layout widgets & utility algorithms. Might be worth
pulling these in too:
