For those of you who have asked for the ability to keep Dapps in your sandbox for longer periods of time (for the sake of editing them or deleting them after the 24 hour period), we’re happy to announce that this is now feasible. When viewing a Dapp that is currently in your sandbox (e.g. after creation), you can click the option to keep the Dapp in the sandbox indefinitely. When you are happy with the Dapp, you can release it to the public by publishing it. The Dapp will remain in your sandbox, open to editing, until you publish it.
This feature also addresses those of you who have asked for the ability to keep your Dapps private. By keeping a Dapp in your sandbox, it remains visible only to you and to those to whom you give the URL.
Enjoy and please do not hesitate to send along any feedback.
