Thanks to Joel Kallman, we got the opportunity to talk about Flows for APEX v5.0.1 during APEX Office Hours on 17-DEC. We got 500(!) attendees and received loads of questions in the Q&A. Some of them got answered during the session by Moritz Klein, some were addressed at the end of the presentation. Still, we didn't manage to answer all of your questions. To cover them all, Richard Allen added a FAQ section in the documentation, so you might want to look over here: https://mt-ag.github.io/apex-flowsforapex/FAQ.html
If you encounter any issues or have any questions, please let us know by sending an e-mail to firstname.lastname@example.org or by creating an issue at our project page on Github: https://github.com/mt-ag/apex-flowsforapex.
If you want to receive updates about our tools, please leave your e-mail address right before downloading the software at https://apex.mt-ag.com/en/flowsforapex.
Thank you all for your support!
The FlowsforAPEX team.
