KakaLVPOT I'm very scared about absent of the topic navigation
Yes unfortunately the "scrubber" is not present in the embed. This is a design decision I copied from Flarum's embed extension, but it's true that it would be useful to still have access to it somehow.
The idea was to provide a minimal look in the embed, and allow navigating to the forum for full experience. The full page can be accessed by clicking the "Comments [number]" title in the embed, but maybe there should be another more obvious button to access the forum.
I am working on an improved embed, but I'm still testing what works and what doesn't. Flarum's infinite scrolling makes it hard to design the iframe in a way that doesn't look like a box.
Regarding tree comments, if an extension implements that feature I will do my best to make it compatible, but that's not something this extension would implement in itself. The goal wasn't to imitate Wordpress comments, it's to provide a different experience similar to what you have on Flarum itself.
