Since I really like Manjaro built-in bootsplash system I made a Bash script to easily make my own custom bootsplashes (is this the correct plural form lol).
For now the script is pretty simple, it'll take a png logo and optionally a spinner (gif). Background is limited to black since I haven't already played with all the settings. Instructions and further info on the repo:
Please, make sure you know what the script does if you wanna run it and feel free to contribute. Any help to improve this is really welcome
There will probably be some bugs since I'm still a newbie in the programming world but I did a bit of testing with some logos and gifs and it all went fine. Hope you enjoy it
