IDE and session expiration

The session to smartthings IDE seems to expire after 30 minutes or so of inactivity. I would like to be able to run an app in the sandbox, unattended, for a much longer time, to collect logging information and to verify that it works well through all the daily events - before actually publishing it and loosing all the good logging capability.
Any chance the session timeout can be made much longer, or automatically kept alive while an application is being tested in the sandbox?
