Several Places where I think a config statement option would be valuable.
This was discussed in previous discussions, but I thought I might summarize and add to at a later date.
A config statement to allow disabling of logging.
value - cut down on size and maintenance of edit/delete log purging.
A config statement to allow disabling of logging of some activity id's that won't mess up other functioning.
value - cut down on size on activity table
A config statement with a string or array of additional devices that allows additions to the mobile array
value - prevent non-mobile view on mobile devices as they enter the market.
also more events on the discussion controller before after user name and time, as well as a title attribute added to anchors
and a removal of a constant that is tied to a definition that can't seemingly be changed without modifying core.
on an unrelated note - it would be cool if you removed the conf/locale.php file from the distribution, so users could create one without fear of it being overwritten, since the distribution locale.php is just a skeleton file, it could be renamed /config/localeskeleton.php with a note about adding defintions and how to copy it to locale.php inside to make it acted upon.
would make it a whole lot easier at upgrade time.
I may not provide the completed solution you might desire, but I do try to provide honest suggestions to help you solve your issue.
