Announcing new file template management for document library content types

Dear all, This feature is quite cool, but I have some additional points on it: - This solution is not supporting the Classic Experience and when you switch to, you retrieve the standard New button options - I tried to load a couple of templates (Word, Excel and PowerPoint) and without any specific reason one of the files are not into the list and can't be retrieve by the "Edit New button" option I found the storage place of the template files using the Classic Experience and IE11 opening the library with "Open with Explorer". The files are placed into the subfolder (hidden folder by default) names "Forms". But when I deleted the templates from the "Forms" folder the items into the new button were not removed, and the Edit New Menu continue to show it into the available template items. So how can we remove an orphaned item ? It was only a 5 minutes test and I have yet some issues Fab
