Hmmm some of the things I'd like to see are things I'm already seeing, so I'd say we're moving in a pretty good direction with webcomics - or at least a lot of LGBTQ+ creators are.
I especially like that there are a lot more LGBTQ+ characters that just ARE, and their identity isn't a huge part of the story. Obviously stories about their specific struggles are important too, it's just that I like having some variety because stories with a different focus will do different things.
What I'd definitely like to see more of is more portrayals of LGBTQ+ characters beyond the L, G, B and binary T, and more varied portrayals of those identities. Not all nonbinary people look androgynous and use they/them pronouns for instance, or at least that's what I've heard a lot of NB people say, and it'd be nice to have some more varied representation.
And being on the aro spectrum and nonmonogamous, of course I feel particularly strongly strongly about this one, but more diverse relationships would be nice. (Lol big surprise that this is coming from me). Aro characters that aren't also ace, ace characters that aren't also aro, characters on the aro and/or ace spectrum that aren't innocent sweet little summer children, stoic and emotionless or completely disinterested in relationships and maybe even experience romantic or sexual attraction but differently. Because I can tell you it can be very different from how an allo person experiences it.
But also aroace characters that are completely disinterested in this stuff, romance- and or sex-repulsed characters who don't just sit by and smile when they have to hear about someone's romance for too long, aplatonic characters, loveless characters that aren't evil psychopathic villains. Stories where romantic love doesn't make you good and doesn't save the day. Ambiguous, unlabeled relationships, partnership-like friendships, QPRs. Just ... Relationships that aren't a clearly defined socially acceptable romance or friendships, and stories that break down the amatonormative rules about what is and isn't acceptable in a friendship or romance and do away with the idea that all relationships need a label and need to fit into a certain box. I don't know, I don't really like it when a story goes "if you feel x then you must be feeling y, x always means y." It's not like that in real life and when it happens irl it can actually do a lot of harm.
Oh, and more nonmonogamous queer characters would also be nice.
And then obviously relationships don't have to be the main focus of the story all the time. The majority of LGBTQ+ stories are still either feel-good lesbian romance stories (which, admittedly, I do love so I probably contribute to there being a market for that) or somewhat sexualising BL stories (which I'm sure have been discussed a lot alread so I'll refrain from that because a nuanced discussion would make this post even more obnoxiously long). But I already feel like we're moving in the right direction with that already. And like i said, I also really enjoy relationship arcs, I'd just prefer it if they weren't forced into boxes so much. Even alloromantic characters shouldn't be pushed by others to admit that they're in love. That's not a cute thing for anyone.
