Rated 3 out of 5 stars
1) Haven't had much time to test more, but I saw at once, that completed tasks could not be identifieed as such!
There was no check to be seen, though the list behaves normally, but uncmplete or complete tasks look the same.
2) The red font is sometimes hard t read on the light grey of the window bars on top. Perhaps skip the fade effect on the bars instead.
Thanks for the detailed report. It helps me greatly. I will look into the tasks issue for the next release. As far as the colors, that was by design. On my system it looks great and I can see everything well. Unfortunately, I only have one system to test it on, so some things may slip by. Thanks again for the great, detailed review! :)
