I just released a replacement for the favorites list, in the form of a minimizable transparent box that can be shown and hidden by clicking the blue band on the right. It should be more flexible and forgiving of different screen sizes than the old version, and it eliminates the annoying problem of the window expanding when it’s first shown due to the initial position of the dialog box being slightly off. Hopefully it will be a bit more intuitive and pleasant to use than that which it replaces.
The replacement lacks a bit of functionality (it’s not moveable or resizeable by itself), but these were mainly ways to fix its problems. Not having a wrench isn’t much of a problem when bolts unscrew themselves.
