Better Attachment Control for Canvas App

PowerApps Canvas has a powerful control for attaching files, but the UI really sucks.  

I would like a an attachment control that allows the developer to configure how the attached files will display within the control.  The existing control lists the attached files vertically.  So to if you expect to have more than a few files you will have to expand the control vertically.  I am always crunched for screen space, so being able to have the control display the files in like two or three columns across would be a life saver.
