JOELLEVIN  Hello,

The mouse pointer not being covered is a bit of an issue currently - but a known one at that. I'm looking into how to fix that. As to your question about if this reduces power usage, unfortunately it doesn't. It is physically impossible to dim a monitor below its lowest native dimness setting (which I'm pretty sure is what the apple brightness controls let you do). ScreenShade works by overlaying and managing a semi-transparent black window over your monitor (or monitors) that effectively dims the screen further.

If you have any more questions, don't be afraid to email me at info@trutwo.com, or chat me up on aim at trutwosw.

Hope this helps answer your questions.

ADITYA MOORTHY  Hi... thanks a bunch for your reply. If I have any feedback I shall surely let you know. On the topic of power saving, can you let me know what is the difference between the brightness control provided by Apple and the overlay you provide. As I understand, the display details are processed by the video card and then loaded on to the memory where each bits of data is processed including the luminescence. If I am talking nonsense here then please correct me. But if this understanding is correct then you adding the overlay should bring down the overall luminescence right? Thanks for your reply.

JOELLEVIN  So I've done a bit of research on this topic, and I believe you are correct - darker screens require less power to display, simple as that. My only comment is that I'm not sure that the consumption level change will be big enough to make a practical difference, but there will definitely be one. Good thinking, I hadn't actually thought about if power consumption would change.

ADITYA MOORTHY  Thanks... Guess it can also be a selling point for you :-)

Once again, congrats on building such a wonderful application and best wishes to you. If you are developing any other application do let me know and I would like to try that as well.
