This extension implements the Trumbowyg Editor. That editor is a lightweight one with only 20kb of size unlike the usual 40kb other editors need. It still offers a lot of features via plugins inlcuding speechrecognition, for example.
Typowyg furthermore offers a plugin that allows the user to browse, upload, select and ultimatly embed or link content from their Google Drive.
Check out the Documentation and the Live-Demo.
