A default option would give the novice user a simple effort-less
post-installation configuring activity, thereby increasing the
usability. Most of the users,primarily non-technical teachers, will
not like to be bothered with technical details of the system. Users
are also bound to make certain changes in the settings for mere
experimentation, which might not quite live upto their expectations.
Restoring Default settings will be a relief.
The default option could be provided on the configuration page in the
form of a command button.
We are very much willing to contribute to the suggestion
implementations ourselves. But we are rather new on this platform and
it'll take us a while to get accustomed to the whole environment. In
the meanwhile, help in any form is welcome.
