Currently in ZapWorks Studio, the properties one wants to animate need to be manually added to the timeline first. The record mode from Unity eliminates that step: once you click on record, a keyframe will be automatically added to the current time for any property you change.
I just thought that it would be a nice QoL feature.
Hi @marks,
Thank you for this feature request! We love it when our users get in touch and work with us to make our tools better!
We have noted this as a request and will look into whether this is something we will add into Studio.
Our timeline flow does work in a similar way. I.e - once the property has been manually added, each time it is edited a new keyframe will appear. But that first step of manually adding would be removed with the ‘record mode’ enabled feature which could be great. 
Thanks again!
George
