Thank you so much for your feedback. what you say makes a lot of sense. I take this into consideration, but it must also be borne in mind that if I load templates into the PWA, the user has to install them every time (although maybe you could do some smart caching, but that's not the only point) and the same thing who use the node.js version.

Please note that you can upload an existing project -> https://tilepieces.net/documentation/panels/package-manager/.... Zip a folder and start editing!
