I'm working on something similar like on-and-off but i'm trying to remove the limitations in usability (e.g. unpack and run)

Features that I for myself want / nearly have:

- My mom should be able to install it.

- Scan from phone, upload to central server / nas

- Everything AES Encrypted when not logged in, decrypted on use (including sqlite database on shutdown)

- Documents can be decrypted with plain openssh, without having the original program.

- Fulltext search through invoices (by extracting PDF text and putting them in SQLITE fulltext indexes)

- categorisation

- built-in PDF reader / printer
