Hey thanks for trying it out and for the feedback! :)
I thought about using environment variables, but I just wanted to do something simple so I opted to go with a filename. It's certainly not a secure option and a bit odd but the encryption part of Jern isn't meant to be perfect, I meant it more for obfuscation and obstruction (someone scraping your files for instance would come across it and not be able to read it, for example)
Thanks for pointing out that part about the Turkish keyboard! Ideally I'd like to make those shortcuts user-mappable so that it can adapt to any keyboard
Navigating older entries is a popular request and will definitely be in a later version :)
Thanks again!
