Extra improved slider

An Adobe Photoshop CC panel extension. Includes RGB and HSB color sliders, a greyscale slider, and a 6-step greyscale slider.

Usage

With Adobe Photoshop CC installed
Download the .zxp file in /build
Download ZXPInstaller (This is just what I used; other .zxp installers may also work) and install the extension. Alternatively, convert the .zxp to .zip by changing the extension, and extract the files. The folder must be placed in "C:\Program Files (x86)\Common Files\Adobe\CEP\extensions" To show up as an extension.
Launch photoshop
Open the panel: Window > Extensions > ExtraImproved Slider

Issues

Switching fg/bg colors with "x" hotkey does not immediately update the panel (requires mouse over to update)
If the background color is selected (panel), but the foreground color is active (default color picker), sampling a color will update the panel's foreground color, instead of the background color.
