No metro apps, I’m thinking of something like Whalebird is for mastodon, but for Lemmy. I’m looking for something that would allow me to be logged in to all my lemmy instances at once and allow me to have one single column that allows me to switch between them.
I think your best options are mlmym or alexandrite installed as a PWA from your browser. I think Liftoff also has a native app for Windows but I’ve only tried it on Android.
