Evernote with text collapsing will remove all other Outliner software. I read all threads, and noticed the original suggestion was made in 2014. Currently, I use multiple software, OmniOutliner (Mac), UV Outliner (Windows). If Evernote introduces the collapsing text feature, I will subtract all other software, and can totally focus on it. Because of shortage, I use Evernote only as a web clipper and simple note taker, which make me remained in free user state. The new feature will boost my usability, and finally make me sign in the premium feature. Thanks.
