Please maintain the GUI

[msdobrescu]

I use p7zip under Gentoo.
I need a GUI there as it was in the previous version, 17.x.
If that is not possible now, just add some desktop services for the basic ops, like decompressing or compressing with some defaults.
The context menus in KDE (in my case) are truly useful for a regular user that would not use the command line so much.
