Is it possible to add a go to top button somewhere (in the blue header or like the edit button) to go to top of the note ?
On desktop version "cmd up" is doing the job perfectly but on iOs nothing like that to my knowledge.
Now that TOC (with the possibility to choose depth - thanks @tessus) allows to have a note easily to browse, going to top is needed
On iOS, you can touch the clock at the top of the screen to scroll to the top on most apps, Safari. Just tested on Joplin with a long note on iPhone 8 and it is working as expected. Hope that helps!
