Currently developing a lightweight control panel, works with Mac OS X (+ Server) & Linux. Has support for monitoring load, uptime, CPU & Memory intensive processes.
It also currently has a process list implemented with sorting by CPU usage and Memory usage and also checking whether a process is active.
Still heavily under development but hoping to have web server config editing (with full support for Lighty, nginx and Apache (all with rewrite support + modules installation)).
Any feedback?
