How do I communicate information to the company about improving their products?

Please read the text carefully.  This will give the added convenience of using the iPhone around the world.

 I would like to bring really convenient features to iCloud Drive - files.  This is what a lot of users want.  Namely, when you try to save an open pages file on a mobile device to a specific folder (no search, no tag).  If there are a large number of files and folders, you remember the name, but you cannot quickly find and save this file in a specific folder.  In addition, not all folders are displayed correctly in the mobile version when saving a file.  If you go to iCloud Drive - the search works, the folder is visible.  However, if you have a file open (for example, word format, pdf, and so on) and you want to save the file to a specific folder or a folder with a specific tag, then the user will not be able to do this, since access to these functions is completely difficult.

 On a Mac, there are no such problems.  This only applies to the iPhone.  Also, when you copy a file, you cannot paste it into any folder.  There is no such function.  In fact, you cannot work with files on the iPhone.
