Starting with version 0.3.0 the GRUB2 Editor has acquired a visual changelog.
This post will be quite straightforward because v0.3.0 didn’t get many visual enhancements; most changes were “under-the-hood”.
The most obvious change is the “Preview” button for wallpapers:
Whenever you change your GRUB wallpaper, click the Preview button to get a bigger preview of the wallpaper.
Next up is color management:

At startup you may notice a new pop-up dialog:
This is in order to retrieve GRUB device names, but I may remove it at some time. Seems that GRUB2 can do fine without explicitly specifying devices.
Lastly, there is now (primitive) support for the GRUB_INIT_TUNE configuration variable:
*ADDED: Allow previewing a wallpaper (=splash image).
*ADDED: Support for GRUB_INIT_TUNE.
*FIXED: Make colors actually work.
*FIXED: Handle better GRUB device naming.
*FIXED: Rewrote big part of the code.
