just added basic support for Pluraldawn indicators to nicolium. by basic i mean it only supports emojis as indicators and doesn't allow remote origins of avatars yet (so it always uses the emoji used for indicator). deployed to pl.mkljczk.pl. it can be enabled in settings->content->parse pluraldawn indicator emojis.
@senil is there anything i can help with? i think i mostly used it with pleroma/akkoma where you can provide the config server-side instead of a static nicolium.json file so the fallback behavior might not be optimal
