Feature request: photo gallery app & spreadsheets

I started to make the move from G drive to Proton but there are two important missing features that prevent me from moving 100%.

1. Photo gallery: backing up photos with proton drive is very straightforward right now but there's really no gallery app. Ideally, we'd need an app that at least (a) allows you to easily see photos for a given month without having to scroll down forever (the fast scroll in Google photos is great for instance), and (b) makes possible to create albums and share them with other users.

2. Spreadsheets: these are totally missing at the moment. A lot of people use spreadsheets in Google Drive to track their expenses and their investment portfolio. It'd be great to have spreadsheets that have (a) functions to access financial markets, and (b) functions to connect spreadsheets together (e.g., give a spreadsheet the permission to read a cell from another one).
