Summary: This concerns the little Post-it icon that indicates the annotation of a highlight in the desktop version but is not available on my iPad version (most recent release).

Details: When I add a note to a highlight on my desktop, a little post-it symbol is added to the highlight, indicating the annotation.
In the iPad app, only the highlight is shown, with no annotation indicated (the note is available though, when clicking on the highlight).

As I use both the Desktop app (on Linux and Mac) and the iPad version, and switch between annotating the highlights and directly adding freehand comments on the iPad, but also highlight plenty of text without adding notes, it would be handy to have the icons indicating annotations on the iPad too, otherwise I forget that I already added a piece of information or a thought to a paper.

I have resorted to drawing a little square on top of annotated highlights as a work-around, but I don´t always remember.
