I think you just need to modify the stickynote_show_notes function. The code looks better and it's more readable.

static void
stickynote_show_notes (gboolean visible)
{
    StickyNote *note;
    GList *l;

    if (stickynotes->visible == visible)
        return;

    if (g_settings_get_boolean (stickynotes->settings, "click-hide") && !visible)
        return;

    stickynotes->visible = visible;

    for (l = stickynotes->notes; l; l = l->next) {
        note = l->data;
        stickynote_set_visible (note, visible);
    }
}

@zhuyaliang Build runs fine with debian at travis CI now. So what we do with the unsolved conversations? Did you fix them?
