To follow Twitter tags with #Fedilab you need the latest release (3.30.1). It works like following Twitter accounts with #Nitter.
In the main menu, open the option "Manage timelines", then check the media descriptions for more details.
You can create several timelines and/or group tags in a single timeline.
@apps Are you planning to release an iOS version?
@Anonymous

@Anonymous @apps Why should you follow #shitter acounts? The more X collapses the better.
