Htop - Manage Your System Processes in Seconds

Almost everyday we use top to check which processes are using more cpu/memory. It's such a basic tool that I have never spend time searching for something better. Nevertheless, I never found top to be very intuitive or fast. The article Htop - Manage Your System Processes in Seconds
shows an excellent alternative. It starts much faster and it's much easier to use than top.
Just to show you an example: if you want to change the order in which processes are displayed, just press F6 and select with your up/down keys the criteria (cpu, memory, etc). Press Enter and voilá. Now try the same on top! Yes, you can do it with top almost as fast, but only if you can remember the weird shortcuts. If you use top ocasionally, then using htop is much simpler and intuitive.
Another example is killing a process: select the process with your up/down keys and press F9.
Just a note for the article author: very good blog, focused and to the point.
