We just started using BPMN.io, works really great. We use Dropbox/Network Share and would love the possibility to ‘Save as… .’ as well as Save changes back to Source
Workaround today is to Open the file from BPMN.io, make changes then Save then, from browser downloads folder Rename File then move to Dropbox/Network Share.
The web based bpmn.io you are seeing at demo.bpmn.io is a simple client-side web application with the purpose of showcasing our modeling tools. Because of that it is inherently limited in what it can do (i.e. save as... is not gonna work).
We may provide more elaborated tooling in the future that can do this but it will probably never be part of the demo.
As for the email: Thanks for letting us know! Can you forward the mail to info@camunda.com with reference to me and this forum?
