The purpose of this project is to make the process of making GRUB themes much faster and easier for the average user. Normally the process would look like this:
Paired with the fact that the iteration cycle is quite slow, this process is going to drive you nuts after a while. Oh, and did you know that the documentation is quite lacking too? Like an entire option was missing and some details are ommited? Yeah this is very fun. /s
It is time to put an end to this suffering. I decided to make a tool for previewing the GRUB theme. While it is possible that the preview isn't going to be pixel perfect, I hope this tool can get you at least 90% there and you can use a VM or real hardware to polish whatever doesn't quite line up.
TL;DR: this is a GRUB theme preview tool.
