TootRain 1.6 is out now, with animated GIF support!
There’re also 2 RIP Tweetrain icons by @Linkzero!
The preferences layout is improved and now you can configurate speed in the options. Misskey v13 is also supported. It still works for older Misskey versions, but emoji in user’s display name may not work.
