Option in Mixdown Dialog window to Open the Folder where the files are exported after it's finished exporting!

Yes. +1

In that context, I find it really annoying that the export path is not saved with the project. When I open Project A and export to Project A/Export, then open Project B, it wants to export to Project A/Export. What’s the reason behind this? I need to go hunting for where my exports are a lot of the time because it exports it to some prior project’s folder. There, your requested button would also help to find them. But it would be great if the path would be per project.
