Export/import project

[xdxd121xdxd]

Right now, it is possible to export/import a board. I'd like it to also work on project.

Thanks for the idea.
Right now, we have many internal feature requests and some requests from out GitHub community that are in progress.
I'll try to look at this in the meantime (cannot give any promises).

If anyone is willing to make a PR on this, I'll review it and add it sooner.
