Adjusting an existing Reddit app for Lemmy is probably an incredibly hard task too, as the APIs and functionality are very different. It is probably easier to give some feedback to the dev of Jerboa (or contribute yourself if you can code :) in order to make it better
Lemmy
Everything about Lemmy; bugs, gripes, praises, and advocacy.
For discussion about the lemmy.ml instance, go to !meta@lemmy.ml.
I know... I'm a senior dev / system architect, I'm just incredibly lazy
Boost was my favorite reddit client, so I based jerboa's ui mostly off it.
Tap and hold the comment title bar to collapse a comment.
That's what I'm using, and thank you for sharing that one! I didn't realize it was a feature, it would be nice to have more options (I can help somewhat as I'm a programmer, but tbh android stuff like apps isn't my specialty). I can help a ton with backend or device settings stuff though.
I did teach myself android / jetpack-compose so I could develop it, being mainly a rust / typescript dev myself.
We could dev use help pretty much everywhere along the lemmy stack tho, the back end, lemmy-ui, more apps, more web uis, etc. Glad to have you!
I'm using Jerboa for Lemmy (android). And there is Mlem for (iOS)
I feel like a crappy salesman by now but there is lemmur, a recently abandoned project for a lemmy client that I think could be rehabilitated with the proper expertise.
The official Android app (Jerboa) now has support for collapsing threads, you need to click on the top border of the comment. You might need to update your version, I think the release is from yesterday or today.
Modifying a Reddit app to work with Lemmy would not be trivial, though it is possible.
