Interesting, yes, but for "log killers"
Seriously, more than quickly deleting logs (I would prefer to keep them all...), what I see with the way logs are stored is a table that could put my server on his knees.
And I don't like that too much...
Maybe an automated storage of logs each X days (with a path that we could setup) would let the table not getting too big, and keeping all history log intacts ?
If someone wants to delete the logs, because he wants a clean table for starting prod site, phpMyAdmin would do that...And I think it's the only case logs should be deleted.
