Thanks for filing these features, @Fabla!
You noted that some of this functionality exists in SurveyCTO. That may be the case, but please note that SurveyCTO is a closed-source fork of ODK. That means that they’ve chosen not to share their code changes with the broader ODK community.
I hear you that you’d like some more auditing features, and we have a series on ongoing discussions that will get such functionality added to ODK in a community-oriented and open-source manner. The first of this is text auditing which is coming soon and as you noticed, there is an ongoing conversation on auto GPS.
What is the old saying? If you want to go fast, go alone. If you want to go far, go together. At ODK, we want to move together...
