Priorities for Desktop

[Maynard Kuona]

Is there any way to set default nice values for apps. I want to run my media player (Net-Rhythmbox) at greater than default priority every time I start it without having to do it manually. Are there any security risks involved in doing so though. Not that I will heed them though. I also want to know how to increase priority for focused windows though. Although I hear the new kernel (2.6) will be able to do that. I hate the desktop being unresponsive, despite me having 512MB of RAM on a 1.2GHz processor. It certainly not about me being short on resources, as I usually have at least 60% of the RAM unused, and have about 80% of my processor cycles spare. I do not know if this is feasible, but surely, it would be good to allocate more resources to programs that are trying to start, by starting them with a higher priority, and then decreasing it once they are fully loaded. These are a newbies thoughts though. Please do not take offense if it sounds silly.
