I downloaded the 1.0.0 one because I assumed Portable meant it was for Android devices. It didn't have a settings button, and the few paragraphs that I put into the first entry yesterday, the first journal entry I've made in years, was deleted when I sat down at my computer today. This already feels like a breach of trust for a program meant to safeguard my thoughts.
I'll give the 2.0.0 and JRNL one more try. The settings tray works, but we'll see if it decides to delete my entry instead of safeguarding it the next day.
