My favorite sidebar addon. However, the default theme is ugly and gives a bad first impression. Please make the default theme Proton or Photon because initially I uninstalled the addon before due to the ugliness and datedness of the "default" blue theme which is reminiscent of early 2000's design. It's ugly and there's no reason to make it the default. Additionally it's not clear to the user where you can choose to change the theme, one must be aware of addons -> scroll to addon and be aware there is a preferences tab.
