While it is possible to modify the default unmanage time window by modifying UnmanageDialog.ascx, it would be nice to have that be an option within the standard "Settings" area of the web interface. In our use case there has never been a time where the default 24 hour time frame is a good choice, and while we can change that file it obviously gets overwritten any time the Config Wizard is ran (upgrades, troubleshooting, etc.). Having it in the "Settings" area would make it much easier to change, make it survive through upgrades of the software, and make it a supported ability.
