I'm curious about the applications collection of KXStudio, but I'm still struggling with my new laptop and it's creepy ACPI support. The stupid dsdt is really messed up and totally buggy. That's also the reason why the last parts of the Aspire tutorial are still missing >.<
But well, I've found some really neat tools for Jack today. They look like they could replace the laditray stuff.
There are no ebuilds for them yet, but if somebody wants to have a look and test them, here's the link: KXStudio:Applications
Some feedback would be great though. Let me know if it's worth to test them. ^^
