 2. `ylva` does not have a proper configuration file that keeps with the freedesktop specifications.
 3. The fact that ylva keeps decrypted databases on disk when in regular use without an automatic {decrypt-encrypt}-on-use option was a problem. If I encrypt the database, I have to keep decrypting it to use the program which is a problem. Hence the `encrypt_on` flag was added to `varuh` (see below).
 4. C is a venerable language but this is 2021 and I would rather program (and contribute) in a modern system programming language like `Go` or `Rust` which takes care of the memory handling tasks and leaves me to focus on the application code. Also I felt it is easier to get contributors to a project if it is in one of these languages as a lot of the Gen Z programmers don't know C. You will appreciate this more if you look at an open source repo written in C/C++ and find that 30% of all code are operations allocating/de-allocating memory.
-5. Support for more ciphers and crypto systems - `Varuh` already supports the `XChacha20-Poly1305` cipher and uses `Argon2` instead of the older `pbkdf2` as the key derivation function. OpenPGP encryption is in the pipeline.
