I hope you'll find them much more convenient to use as a full fledged module in a hosted repository. After you install the module be sure to add the ISE Theme Menu to the ISE by running "Add-ISEThemeMenu".
With the move to this repository came the need to conform a bit more to established standards and modify the script layout. Fortunately, Ryan Yates offered to help to tidy it up and did a fine job. You can catch his blog here: blog.kilasuit.org . Be sure to watch that space in the coming days as I hear there might be a mention of the ISE Themes Cmdlets. ;)
One last thing... Since the PowerShell gallery lets me assign my own icon to the module, I thought I'd play around a little. Ladies and Gentlemen, introducing the "Tie Dye PowerShell logo"!
