I have mentioned this before. But I use thunder. It doesn't have emote support but it atleast shows them properly and I can save them as images to use em.
nah we are the only ones that use them heavily last I checked so its never been a priority for anyone else. One of our devs developed the feature for the web UI/backend, and they don't seem to place that much importance on feature parity in jerboa.
It's open source though so if anyone is interested in attempting they would probably accept the PR
