Say cheese, cheese, cheese!
Streamer Mode
Disable opening files to not let viewers see your .envs!
How do I use this?
Right click and you'll see the Streamer Mode: Toggle Visibility option.

After clicking, all tabs opening the file will close- the active tab will change into the No Peeking! panel.
This is indicated by the X mark next to the file.

It will automatically hide .gitignored files! Here's are the additional marks next to the file/folder.

Don't want the files to be .gitignored but still want to save the sensitive file locations in a file? We also have a .streamerignore for ..well, that!
(I recommend maybe .gitignoreing your .streamerignore.)
Settings
Enable Streamer Mode: streamerMode.enableStreamerMode
Self explanatory, I hope.
Show Blocking Panel: streamerMode.showBlockingPanel
Show the No Peeking! panel.
WARNING: The panel only shows up for tabs opened after it is hidden, if the tab is active (It's just a tab.isActive check in the code). Super hacky, Beware!
Blocking Panel: streamerMode.blockingPanel
The settings of the No Peeking! panel.

There's also optionally a Show Anyway option!

Commands
Enable Streamer Mode: streamerMode.enable
Changing the streamerMode.enableStreamerMode setting will also call this command.
Disable Streamer Mode: streamerMode.disable
Changing the streamerMode.enableStreamerMode setting will also call this command.
Clear Streamer Mode Data: streamerMode.clearData
The files/folders hidden in persist in each workspace (it stores an array of paths in workspaceState). This will clear all the data (basically just state.hiddenFiles = []).
That's it! Thanks!
