KDE Bestever Slick Line Plymouth Theme
Source (required if based on other people's work):
KDE Bestever Slick Line is inspired mostly by KDE but it can be used even if somebody is not a huge fan of KDE, it's a slight modification of KDE Bestever
I've just noticed that on some displays on preview it looks like logo isn't centered but it is so on the bootsplash, awa if you zoom the preview, you'll also see this.
Don't be shy, give it a try, hesitation isn't good for you, trust me, I'm a doctor ;-). I believe in you capability to download and set it up, after all what have you got to lose, if you don't like it you can always delete it and once you change your mind, bring it back.
*QUITE IMPORTANT*: Do you like it? Definitely check this >> information. You may also pling it.
IMPORTANT NOTE: If you voted out of favour because you had a bad day or acted upon feeling like a spoiled toddler, be aware that I consider it as indeed very immature and silly. On contrary, if you liked what you got, definitely feel free to vote + and possibly point others to the product site, you will actually do well if you do this, unlike most who in fact can't do anything else than express negativity because they think it matters.
