Hello!
It's been a long time since this save editor was created, I think it deserves a proper post about it.
Pripara SE was my first tool for modding, after this one I couldn't stop developing my own tools for file editing.
For my luck, Pripara: AIPS save file had a very simple structure, it's even possible to create all the save file programmatically, and that's rare by my experience.
I used list views for each array list and would use images to make the user's life easier, but I wanted to avoid any use of external content in the software.
Instead I've created a document with all the ID codes, and the user can use it to add new items to the save file.
