I still havent find a software that can do what I want:
- organize treeview entries, where treeview entry can be a text, pdf, doc, jpg, xls, etc
- open the files inside the program, in a view pane
- be able to edit the files inside the program
- be able to add notes
- save all the above files and treeview data into a single file
I recently figured out that reference management software may have similar structure, but I didnt find any (the internal viewer part is the hardest)
any hint?
