Pro Palette color cycling
GraphX2 being based on older 256 bitmap software has inherited some tricks that modern pixel editors do not have . One of them being the ability to cycle color palette and produce animations and effects with it.
Pro Has a great palette tool
You can create gradients from one color to another, work in either RGB or HSL color space, save and load palettes, sort and organize palettes, and even work on "color cycling" images.

Theme UI style can easily be changed from settings including buttons and colors.
Pro Drawing constraint mode for vintage 8bits machine
The program is able to enforce the pixel constraints of old machines (C64, ZX Spectrum, Apple II, Game Boy Color, etc.)
For example, in ZX Spectrum mode, only 2 different colors can be used in a 8x8 pixel block.
Pro Innumerable button-click file ops are integrated
Rename files, move to other directories and extracting archives are of course a given...BUT THERE'S MORE! Convert media formats, make symlinks, CHMOD, change graphic formats, integrated GPG, filename UPPER/lowercase adjustments and more with just one button click!
Pro Remote access
Worker supports access to remote machines through various ways (ssh, ftp, rsh, http and webdav).
Pro Low system requirements
The system requirements for Worker are pretty low, making it a great option for lower-end machines. The reason why they are pretty low is because Worker is basically made of just X11 libraries.
Pro Configuration GUI
Worker has a built-in configuration GUI.
Cons
Con Dated look and feel
It looks like it was never supposed to be used in the modern world.
Con Lack of modern features
Some modern features that are necessary to do pixel art creation for game dev work are lacking.
