How to get Google Drive apps on multiple accounts

I came across what seems to be a serious usability problem for users trying to use the Google Drive app from multiple accounts. For an application to use Drive APIs on behalf of a user, the user must install the corresponding Chrome Web Store application during login as that user. The problem is that the Chrome Web Store seems to be looking for the application installed for each browser, while the drive’s API requires the application to be installed for each user.

As far as I can tell, the only way to install the same application for multiple users in one browser (Chrome) is to install with one user and then log in as a second user, uninstall the application (which CWS says it’s already installed), and then reinstall it (so that the disk marks the application installed for the second user). This is a very confusing experience because during this process the application and CWS send mixed messages to the user about whether the application is installed.

I am not sure if there is a canonical application for testing such system errors. Does DrEdit live somewhere? But if you want to see the problem in our implementation, install the Graphing Calculator on Desmos.com as a single user, run it and log in using google drive and make sure everything works. Then exit the application and use https://accounts.google.com to log in to Google as a different user and try using the application again. The application will tell you that it is not installed (what the APIs tell us) and directs you to CWS, which claims that the application is installed.
