I had to experience yesterday that using the application to change the Menu timeout will not simply replace the value of GRUB_TIMEOUT but it will also replace GRUB_TIMEOUT_STYLE=menu and turn it into a duplicate of GRUB_TIMEOUT.
This happened to me on Version 0.1 of Garuda Boot Options.
Besides that the About window of the application has no working hyperlink, no working license and changelog button.
The Help button is also non functional
