Not being able to change time between sessions is a huge deal for me. Also, the current default of 30 minutes seems pretty counter-intuitive.

If you cannot make the time configurable, is it possible for you to hard-code the default time to something closer to 5 minutes instead?

If not, this is likely enough for me to check out Holdem Manager.

That value is not configurable at this time. Changing it to be so would be a large undertaking.
