Editing previous notes of a file

Hi, I am new to Tropy, and just try to understand how it works.
I have just noticed that when edit notes first entered with the image file, the changes or additions do not survive after moving to the next page in the (pdf) file, or to the next document.
Do I miss something? If this is a programming error, it would be fatal.

Notes are attached to each image. When you select the next page the note in the notepad switches to the first note attached to that page (or to a blank note if you haven’t added any notes there), so this is by design.

We’re going to introduce item-level notes in the future; item-level notes have a big impact on the way the navigation in Tropy works so this will be released together with other UI changes and at this point I can’t say which release this is going to land in.
