Not really. I think the feature makes sense, and I like that this will only *substract* from the set time (so not exceed any set limits).

I'll leave picking that number to you.) -Steffan --fqnlKP6k7mP6a7sIPnVOPPLUcxP4gusO1-- --PfCMqmB62snG9HlRPLXktMJlcbPbgeBfQ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJY5J1SAAoJEEEwndWOY1w5w8IH/jODa1iO25uweOdXTUIUoHcO IdDEfVGtDj3detAYivqZjf1Zq22iUnb7kfOAyy7wZKfgraEOGhtZUcilau2jkPiI XVBlhfO8odqk9PdZPMe2+IF9Aq8huIjOjocMEd0R2jpGpglTeaAfIqLNV/PRbNiD 1frOTSAJvbUdA3e1p9W95hknSPn2T691KsGqux53EVSG3gW9LZBSET2+fZugbcg9 nVCnGpKFhqRVpFjNCF1eKJBlI4OzY6hW6TpKspIo2J2hURUDrVQRSrND9+Q2+P2Q +nLrXKBZTR0Ty1bXKVvAyR6ZERcQ9KQh3e3hheRcqYmtx74jl5y4PWUz08dTICI= =SZak -----END PGP SIGNATURE----- --PfCMqmB62snG9HlRPLXktMJlcbPbgeBfQ--
