I'd much rather have my machine finish the thing i just asked it to do in less time by default, than wait around twiddling my thumbs while the machine has spare cycles. The context switch for my mind is way more expensive than the context switches going on within the computer. The change from 2 minutes to < 30 seconds is a game-changer in terms of keeping me focused while i'm developing. make it easy to do that! --dkg --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEARYKAB0WIQTJDm02IAobkioVCed2GBllKa5f+AUCXNCgDQAKCRB2GBllKa5f +NXPAQCgobp3ihX7Hcq2U2jM6kJXrXEfNOG2bvgRnzuPmfbRjQD+Lt/2e3CW98tG 3qVWyJCLSq9JnfGDgGaHkzW9wNnW+gY= =h1d5 -----END PGP SIGNATURE----- --=-=-=--
