Haven't found a GUI to customize the new login screen.
Settings are located in org/ArcticaProject/arctica-greeter
in dconf-editor
for those that want to tweak it (be careful or you will break stuff).
Some things I noticed.
- There's a bug in Caja since 19.10. The first time I right click on the recycle bin, empty recycle bin will be missing. I have to click again on it in order for this choice to display. Don't know whether it's related to my language or not.
- When you click on the shutdown button in the panel, Éteindre... (=shutdown) has been replaced with Arrêt en cours... (=ongoing shutdown...) which doesn't make sense. Wish I knew where to fix this on Transifex.
Other than this, it feels polished to me and great to use, as usual.
