From the change log: "Removed the sidebar and added floating buttons instead. Now the notebook is accessible from anywhere." I'm not seeing any button that gives access to what was on the sidebar.. There are two buttons on the upper right side of screen that go to the save/load screen and the info (notebook). Yes, there is the abbreviated version on the top screen bar, but the side bar was more informative.
Also, I don't think access to saves from v0.1 works because the v0.2 folder name is different from the first version and the htlm doc name is index, where the first version it was called elixir of life. At least this is true of Firefox.
