I have migrated all my files from Google Drive to Proton Drive, and am happy with the security Proton provides. However there are a few features that I found don't work in Proton Sheets that I relied on in Google Sheets.

1. Please add a Group function in Proton Sheets - this is the Excel function where you can hide / unhide a group of rows or columns with one click. Many of my Excel sheets that I moved to Google Sheets use this functionality but this is not a feature in Proton Sheets currently.

2. Improvement - Conditional Formatting - In Google Sheets, I can see what specific conditional formatting applies to a selected cell by right clicking on that cell, and choosing "Conditional Formatting" from the menu. What is displayed is ONLY the condition formatting rules for that selected cell. In Proton Sheets, when I do the same, it shows me a very long list of ALL conditional formatting rules across every sheet in the entire file. This is too much information and unnecessary. Please fix this by only displaying the conditional formatting rule that applies to the selected cell.
