Those are good questions!
While designing Tropy’s UI we have put have a lot of thought into the correlation of notes and photos, but we are still working on a final verdict on some of the issues involved. This topic becomes slightly more complicated with the addition of ‘Photo Selections’ which we are about to release with the next beta (scheduled for this week): basically, this allows you to select a part of the photo and attach individual metadata and notes only to that part. If you have a photo with multiple ‘selections’ and attached notes (e.g., transcriptions) it would be very confusing if activating a selection would not automatically bring up the corresponding note (and vice-versa). For that reason we’ve decided to always link photos (and selections) and notes.
In other words, yes, there is currently no way to open a photo while showing a note that ‘belongs’ to a different photo. We discussed a few ideas that would allow you to detach / re-attach notes from photos but have not found a solution yet that would not result in confusing UI.
Having said that, this discussion has not been closed and we are very much looking forward to the beta with photo selections, specifically, because it will allow us to try out the UI with multiple photos, selections and corresponding notes.
Obviously, it is a big help to learn about your experiences and use cases to inform this discussion. For example, we made the assumption that, when transcribing a multi-page (multi-photo) document, you would create multiple notes, transcribing each photo’s content. Once everything has been transcribed you could then copy all the notes into a single one if you prefer to have the text as a single note (but thereby losing the individual associations of photo and text).
Thanks for the feedback regarding the note pad: we are still working on the issues regarding focus and cursor position that you mentioned.
When using undo/redo in connection with notes, please be aware that the undo/redo works slightly differently depending on whether or not the note is currently active: if the note has the keyboard focus (i.e, because you’re typing) undo/redo will undo only the most recent keystrokes, whereas if you leave the notepad and issue an undo all the most recent changes to the note will be undone in one batch.
