I'm frustrated when I'm in the middle of using or editing an app and the LOWCODER_COOKIE expires, making me log in again.

The LOWCODER_COOKIE expiration should be reset based on LOWCODER_COOKIE_MAX_AGE on any user activity.

I've tried setting the LOWCODER_COOKIE_MAX_AGE to a larger number, but that still expires at some time and forces a login even when I'm actively using the system.

The LOWCODER_COOKIE_MAX_AGE is necessary, as we DO want users to have to log back in after a certain period of inactivity, so setting it to something like 9999999 defeats the purpose.
