The ease of creating and editing drop down menus in Google Sheets is so far unmatched by Proton and is keeping me in the Google ecosystem.

Making changes to Google Sheets dropdowns is very easy and intuitive - when selecting a cell, each dropdown option is displayed on its own line, with the option of dragging and dropping to change order and edit the options as their own fields, rather than fields being comma-delimited - and there is the ability to color-code each field so that the contents are easy to differentiate, rather than the current Proton setup simply being plain text over the color format of the cell. It probably seems like a small change but would be an immense relief for me - it's really just a few small but important details keeping me with a foot in Google.
