This package lets you easily extract .gz files and then open the extracted file in a new tab. The files are extracted into a temporary directory.
The package will not attempt to open .tar.gz files, as that would interfere with the archive-view package.
You can also gzip-decompress a file by using
cmd-g cmd-d, or by searching for
Gz Opener: Decompress in the command palette.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
