We're using bird names as a convention for our projects. Which may or may not be the name of the apps. Frogmouth felt more memorable than "mdbrowser" or "markdown-view"
This may just be a personal quirk, but many of these sorts of names to me seem to be one-way memorable. Like, if I see a future reference to "frogmouth" I probably will think "Oh yeah, I've heard of that." I may or may not remember that it's a markdown browser. But if I'm trying to remember "that markdown browser I saw a while ago", I can rarely pull out the name "frogmouth".
