Yeah, that was just a suggestion for you at the present moment while we don’t have the feature available. I’m definitely not trying to dismiss your point… I agree with you that implementing sharing would make the app more powerful and easier to use.
To answer your question in another way, though: odrive gives you a way to combine and share your storage in a different way. So if you wanted to create a drive to share some specific folders (e.g. one folder from somewhere in Dropbox and one folder from somewhere in Google Drive) with someone else, you can use odrive to easily do so. Your files can remain where they are in whatever storage that you use to organize your own data. But when you want to create a custom cloud drive with specific content from specific places in one or more different storage sources, you can use odrive to do it instead.
Replacing native clients is something that a lot of people are interested in (especially when offered the capability to share, backup, encrypt, and sync with any storage when fully realized), but there are also ways and reasons to use odrive even alongside native clients (if a native client happens to have something the user needs or can leverage).
