Direct File Access from Cloud Storage

[mailh...@gmail.com]

I want to use Epsilon to create, edit, and save text files "-directly-" to Dropbox (and Google Drive). I do not see how to do that. [I am not referring to the Export or Import actions].

DETAILS:
The Dropbox Button accessed via the Files Browser opens Dropbox as if from an embedded browser in Epsilon. However, the resulting window lacks the "Create new file" normally found in the browser view of Dropbox online PC such as a Mac with Safari. Though I can read and copy text from a file in Dropbox accessed by that button, I cannot see how to directly open that file in Epsilon to edit. [The lack of a "Create New File" button seems to be an issue with Dropbox mobile web as the same result occurs with Chrome, Opera and other browsers on the Galaxy S9 running Android 9.

I can open existing files from Dropbox and Google Drive via a file manager such as Solid Explorer and choose Epsilon to edit and save back to the respective cloud storage.
However, I expected to be able to do this directly from Epsilon, at least the files in Dropbox directly into Epsilon as can be done with iA Writer or JotterPad.

I had also hoped that the Default_folders_window [accessed via "File Browser] would have accessed the "Folders and Files List" from Dropbox (and Google Drive).

The Default_folders_window gives a list: "Device storage, Buffer, Downloads, Storage 1 and Storage 2." Is there any way to assign Dropbox (or Google Drive) to one of these, or add a "Cloud" line or two or "Add = +" function to the list or in preferences [renamable once they are set-up]? so that the folder view of that cloud storage acts in Epsilon directly as do the Device storage and SD card storage accessed from that list?

I can add a link in the index.cm file to open to Google Drive but that opens in a browser or Drive app. from which opening a text file is not directly to Epsilon. When I click the edit button, the choice of apps to use does not include Epsilon unless I find my way to "Open with"
Though as I already said, the same file opened via Solid Explorer does give the choice to use Epsilon.

I can export via the File Browser "Choose Action" Export file to SAF. However, I'm looking to work directly and not have to Export to get files into the cloud. Besides, if Export is my workaround - Solid Explorer gives me more options.

What am I failing to understand?
Is there a way to interact directly from Epsilon with the Dropbox files?
Create, edit, and save. [and google drive]
This is important for collaboration and working from a variety of different access points.

Thanks,
Marc
