    ui.bufferselectors: Add a TODO for fixing our duplicate UI files
    
    There's a few issues with fixing this. The first and more serious is
    that there doesn't seem to be a way to have the template of e.g.,
    FilteredListSelector used for init_template() when subclassing. The
    other issue is that I couldn't figure out a sane way to access objects
    declared outside of the initialised template scope, such as the tree
    model.
