PowerApps are good till creating custom forms and applying conditions but they lack supporting folders no matter in which folder you create the item it still sits in root level and I'm not able to find any type of way to link up two forms or create a subform.
If you guys can consider implementing this then it would be very helpful.
Are you asking for the ability to connect directly to folders (if so which data source), or the ability to link two forms to one another? (Side Point: We can track these best when there is 1 feature request per idea.) If you meant the later, can you share an example business scenario where you would use a subform please? Also, let me know if you are using both canvas and model driven apps.
