Jerboa is a bit hamstrung because it is written by the main lemmy developer who, understandably, has had to spend most of his available time dealing with the impact from lemmys sudden growth
What's wrong with Jerboa? Genuinely asking, I've been using it since I discovered Lemmy 1.5 months ago, and only had a problem once when the instances were down due to a critical vulnerability bug or something that happened last month, when I had to manually log out and log back in to fix it.
