Suggestion: prefix commands with Snowboard

[rlh1994]

The commands in the command palette can be a little difficult to discover if someone is not familiar with all the features of the package, and this will only get worse as more commands are added.

Many other packages use the extension name as a prefix for their commands to help keep their commands together and allow for the user to explore more commands they may not be aware of.

If you are happy with this suggestion I'm happy to make the basic changes needed, but I have not developed a vscode package before so am not sure if there would be further work beyond simply incrementing the version number in the package.json to increment and release the package.
