To make it clear: This is nit-picking, but my eyes are always rolling, when reading "Als Paket speichern" (Save as Package). Tststs ... Germans.
First of all, a "Paket" means to me something closed, which is not true here, as the folders are open. If the "Paket" would be (automatically) zipped, then I would agree.
Second, the APu video tutorials (German) are saying here "Sammeln von Ressourcen" (Collecting resources). But we are already talking about "Sammeln" in "Ressourcen verwalten" (Resource Manager). So Serif should have an idea on consistent wording.
Third, when you finally determine the folder to save in, the button is called "Paket", which is no verb (Packen). See image.
How about "Projektdaten sammeln" (Collect project data)?
