Floatplane has made a very conscious decision not to influence the user's decisions on consuming content; there's no algorithm, recommended videos, or trending page. you just have access to the videos of people you want to support.
In that sense -as others have mentioned-, it's functionality much closer to a 'Video Patreon' than it is to say, a youtube alternative (AAMOF they've explicitly mentioned that several times)
When seen through that lens, it becomes apparent that "looking good" isn't really all that relevant, I mean, would the way patreon looks prevent you from supporting your favorite creator? probably not.
PS: Of course I get that good UI/UX is a must these days, my point is that they probably have much higher priority (not to mention mission-critical) tasks on their to-do list right now.
