Hi fotostef, nice feed back!
We did put a lot of thought into how to make the posts appear better on other front-ends and we still may do some work to address that. But at the same time, I've always appreciated posts with pictures first then the text. It's still early days here, but I think it may end up being a non-issue if the liketu demographic grows large enough (and our front-end continues to improve) that people may just choose to accept the formatting as is and use whichever front-end to suit their needs.
I hope I was helpful!
Good luck with your project, I am sure it will only get better over time :)
