This idea has been touted in different flavours over the years (but not implemented), but I'd like to push it a little further:
1. Create the ability to collaboratively edit an Alteryx workflow - e.g. like you can edit Microsoft documents collaboratively. If the front-end is primarily an XML interface, this should in theory be possible?
2. Version control (not version tracking) - i.e. automatically state the differences in scripts between versions and allow for checking in and checking out of code
3. Power BI & Tableau Prep have the ability to see exactly what changes were made and to reverse steps to get back to a specific stage of development: it would be great to have a panel that tracks all the edits you've made since you started editing the workflow
In simple terms, a modern, interactive way for multiple developers to work together, but also to encourage the use of Server to "check in" your application and to avoid developers saving the same file over & over again locally.
