There is no way to remove this column as it is vital for the sharing of Workspaces/Collections.
The Initial value should be used for all data that is not sensitive, for example, if you have a generic endpoint for your request this should be saved in the Initial Value field.
Passwords / API Keys and Usernames on the other hand, should be saved only to the Current Value column. When you export or share the collection, this Current Value data is not shared, compared with the Initial value which is shared.
I’m not sure if this is the expected behaviour or it’s an issue in the UI. I’ve not looked through the Issues to confirm if this has been raised by someone.
To confirm, it’s a not a “bug” that the environment quick view doesn’t respect column hiding in MANAGE ENVIRONMENTS , and there isn’t a way to toggle value columns in the quick view right now.
I just filed an FR to add support for this. Check it out, and feel free to add your comments and feedback!
