Just for fun, if you choose to design a wizard, it might be helpful to play around with Picard’s executable commands. You can find the list in the docs.
These let you tell Picard to execute actions like loading files, clustering, looking up, saving, etc… from the command line.
This way, you could start very quickly with a very simple UI and just a few essential buttons that run these commands and then iterate from that.
The cool thing is that even if Picard is already running, opening Picard again with new executable commands will just send them to the instance that is already running, like this:
Maybe there are better ways to do this, but I think it’s useful for making early proof of concepts, as you don’t need to touch Picard’s code at all.
