Hello,

We've created a prototype for a local history functionality for the jbpm-designer, we needed it for multiple reasons. It stores data in the browser localStorage, so it also serves a bit like 'undo after save'. It checks the json representation of the process every minute and if it differs, it creates a new local history entry, including a thumbnailed screenshot. It's available after browser restart too, so if you accidentally close the browser, you can still restore your work.

Here's a small screenshot.

Needs quite much elaboration, but it's already functional and useful for our needs.

If you find it interesting, we'd be happy to share it with the community.

regards,

Gabor Farkas
