Let me expand on the storage mechanism, and its history.
Formatted notes are stored as HTML files within Google Drive. Quick Notes are stored as the Description of a Drive file, so to Drive it appears that a Quick Note has no contents.
This might sound odd, and in many ways it is, but there is a reason for it. The Drive API that Google publishes for developers is beset with performance, reliability and quota issues, that developers such as ourselves need to work around in order to create great products. The first Beta of CleverNote took the obvious approach of storing notes as Google Drive documents, ie they were editable as Drive documents. Because Google uses a proprietary (and undocumented) document storage format, every time we exported a document for editing within CleverNote, and re-imported it, formatted was being lost. We also suffered from duplicated and lost notes due to another (still unresolved) bug in the API.
In the end we, somewhat reluctantly, took the decision to reduce the API usage by storing Quick Notes within the file Description. This was based on a policy decision that CleverNote's use of Drive for storage was independent of using Drive applications (eg. the "Write" application). As we move forward, we will be introducing additional note features such as check lists on steroids, which will be a cross between the simple checklists that Keep provides, and a more complex structure that hitherto you would probably have stored in a spreadsheet. We are currently prototyping the various Drive storage mechanisms to determine the best approach, but again, it will be reliability that will be the most significant factor. At some point we may even offer alternative storage back-ends such as DropBox or even ownCloud, to allow users portability between providers.
We do understand the concern about potential lock-in, and we will be adding an import/export feature that will allow your notes to be converted to/from Google Docs to address this.
I hope this background helps, and thanks again for the feedback.
Kind regards
