is there any way to just save these and continue later?

Yes,when you click save...There is two options one is save online the other save and publish..click save online to just save, and save and publish to upload it.

thanks mate. should have just pressed that instead cause i was wondering if it works like that.

no worries pal ;)

just so you know, when you save a piece for later, it doesn’t save your colors
the colors all go back to default

good to know. thanks mate
