As a moving user from Google to Proton and as a android user, I frequently use the photos.google.com to quickly access the google photos web site and get on my computer pictures I took on my smartphone.
Could you please create a entry in your dns photos.proton.me that redirects to https://drive.proton.me/photos .
This little redirect will offer a direct link to user's photos and will bypass 2 heavy clicks...

thanks
