Labels/Tags are a product feature, not part of email standards. Meaning: it’s not a thing when looking at the raw mail server data.
Each product handles this in their own way, and the tool being used to export your mail from one host/product to another would be what is handling that, if at all. Gmail probably just uses folders because that is part of the structure a mail server would have.
I believe Proton’s import tools handles this correctly from Gmail using both labels as folders and preserving tags, but I believe Thunderbird just puts them in folders as is standard.
You can double check by looking at the raw data exported from any mail service. You could probably easily write a quick script to handle getting tag info and applying it yourself, though it could be quite slow.




















Steam Deck runs Arch at its core. The distro has nothing to do with it.
How you have Steam installed might though. Do you have it installed via Flatpak by chance?
