It would be nice if title can be filled automatically by the first line of content. Evernote does that, very convenient.
Do you mean web-client?
This should apply to all clients, web and app as it is an convenience feature, if you think about it, if it fills out title automatically great. If you don't like it, you change it.
As of now since it is default as "New note" always which is a pointless title, every time users have to change it to something else more meaningful.
We have this feature in web and mobuile clients, We will add to PC too.
