Agave is a Linux application for easily designing and saving color schemes. It provides users with the option to select web safe colors, Gnome icon palette, Visibone or Tango theme Palette. Once selected, you can generate color schemes from a single color selected from the given graph and save color schemes using the Add (+) option. In other words, Agave acts like a color picking utility, which is often found in applications like CorelDraw, that enables generating color schemes based on the selection of a single color block. Once you select a color, adjacent blocks are automatically filled with matching colors, which makes it possible to select a decent color combination, without endlessly pondering over a combination or going through a laborious trial and error process (for matching colors).

Sometimes, the maximum netbook resolution can be inconvenient for the end user. This is particularly the case for people who suffer from a weak eye sight. Newrez is a Nautilus-based script that enables enhancing the screen resolution of Linux computers by specifying a resolution higher than the available resolutions. For example, if your maximum resolution is 1024×600, then you can scale it up to 1280×800 or higher (depending on your eyesight). The good thing about Newrez is that it does not overclock the actual hardware of your laptop, and instead, it builds an image with a higher resolution, which is located in a buffer. This image is then scaled to fit your screen for better visibility. This means that you are not constrained to standard resolutions anymore.
