I'm not going to lie, an "in-page composer" was something we debated implementing a long time ago.
At that time, the composer was still a baked-in part of NodeBB, so it was down to choosing one or the other, and a separate composer (w/ taskbar integration) won over the in-page composer.
But now that the composer is separated from core, this is a possibility once again, done through a plugin.
thank you for the response
in case someone do it as a plugin will be nice but i think the defaults one need some love too
some test video, here at the community and on this topic, homemade, sorry for video quality
iphone 5S, google chrome, no way to edit cause full text not showing
iphone 5S, safari, quoting ok but no way to search full text after a few tries
ipad air, safari, flickering on first tick, then madness can happen, this one lets you move around the quoted text though
It is not a criticism because I love nodeBB but should be a priority to write well in a forum
