@miki awesome tip, thanks! I'm not sure if Toga is a particularly new kid, I mean compared to WX sure, but overal, it's around for nearly a decade, so there is some development behind it. I think I actually stumbled over it in the past as a part of the Beeware project, though I didn't really give it much attention since many similar projects had been just handmade canvas based GUIs back in those times. However, I gave it a try and the accessibility truly is impressive also on Linux. I can't say I'm particularly happy with the programmatic side of things, I mean the components themselves are nice, but styling and logic is too much intertwined to my liking. But maybe I will get used to it after some time, the results seem worth going throug some drag.

@Alleycats @Mayana exactly. Because we're primarily interested in the already familiar elements, which we're expecting to see either grow or act in different contexts, both can be super-fun if written well.
Abstractions can be interesting too, but they may be harder to see through. This is something I find a bit exhausting when reading space scify, they can be really great, but so much things, even as basic as lamps, need to have their own futuristic names, it can take a whole book just to familiarize oneself with the environment. Indeed that's a different example of abstraction than borrowing character names, but I guess implications are similar.

@Caoimhe there have been few people who got to walk on the Moon, but thousands who had been working overtimes to the point of absolute exhaustion, every day, over decades, to get them there. Anybody could hardly remember all their names even if they really wanted to. Yeah, unfortunately, so much awesome ground-breaking work never gets under the spotlights.

@Alleycats @Mayana maybe it would be interesting to ask the authors directly? Usually when characters / universes are borrowed, the reason is the author either wants to evoke emotions / background related to the original, or may want to redefine the character's story because they don't like it in the original or got an idea to make it better. But if there's truly no apparent resemblance in things to the point where it's obvious say the borrowed character is not actually the suggested character, but someone completely else, perhaps there's a higher symbolic the author wanted to express we're unable to see? I think only they can tell. I have myself written several stories, where I borrowed a surname of a famous literature character. Neither the universe, story, nor any of the characters had anything to do with the specific person the surname was referring to, the reason I used it was it evoked certain (though not all) properties I wanted my characters to have. Indeed, I wouldn't mark my work as fan fiction in this case, but classification can be a matter of subjectivity sometimes.
