The purpose of "Developer Mode" is to let artists, labels, or merch companies edit our template code without fear of something being undone in the future.
We understand that many people want their store to have a unique design and we support our users ability to do so!
To balance our need to keep things up-to-date with the freedom of our users, stores in Developer Mode are sandboxed and do not receive automatic bug & feature updates.
Fret not devs! - all of our template updates are available on GitHub for you to merge into your custom theme at any time.
