Totally agree on this one. I am a premium member for years, and I have collected thousands of notes. In my work I want to be able to search through them quickly, attach every type of document (pdf, ppt etc) but also want to have a clear overview of each note via collapsible toggles. I think evernote should really put more effort into improving its hierarchical structure outside and inside a note, in order to keep up with the user- friendliness of its competitors.
Of course you could suggest that there are other apps on the market for this feature, but I find that for example an app like Notion does not have the capability of searching as quickly as evernote does, and also this app cannot store all type of documents.
And ofcourse, I would really like to stay with evernote after all those years, but workflows are evolving...
