Yes I also think the mobile editor is still too basic, and I tend to rarely even try to use markdown when I am editing on my phone. There is a lot of discussion on this forum and github issues already that suggests stuff like: a toolbar for easier markdown editing or even a wysiwyg editor. My personal preference would be wysiwyg but if a toolbar with at least some of the possibilties of the desktop clien is easier/faster to implement, I would be very very happy and finally could really use Joplin on my iphone and ipad. Well, if you come from Evernote than you unfortuantely are a bit spoiled which is my personal problem I guess, but still I think Joplin is a very very great tool already!!!
Here @laurent said something interesting and I am curious to here news about the progression of react native text input. Where there any useful improvements since March?
BTW this thread also discusses the same feature request: Feature Request: List continuation on mobile
