Chrome hosted app
The hosted app for the Chrome Web Store enables users to exceed the paltry 5MB quota that their browsers allot for IndexedDB and/or WebSQL. QMachine (QM) does not require that this app be installed in order to function correctly, but if your workflow uses either of those in-browser databases, you may find the app to be very useful. Otherwise, this app's main use is to provide a clickable bookmark. Future versions may re-enable QM's offline execution mode.
You can find the app here.
