Felli current behavior replaces the console div each 10 seconds even if it has updated or not. (Ajax response)
This is basically a result of me lacking javascript skills.
I am rewriting the UI for the next release though, using mithril for routing and requests, and as it looks now, new behavior will be that it only loads new content if there is any 🙂
I use the pockethold project to learn more web development, and I believe it works, though in babysteps.
