Additionally, all the options under Layout > Flexible Height require the template to be completely reconfigured. Why isn't there an option under Properties that you can flick on to enable flexible height for templates, instead of having to completely reconfigure the gallery layout?
I've already configured my gallery (as it was autocreated as part of app creation), and now want to change the template height to be flexible. I shouldn't have to completely reconfigure it. At least bring back the ability to use a formula to set the template height, so users can use the Title.Height + SubTitle.Height + Description.Height + 20 method.
