"Open" button not available with sudo

[luochen1990]

I have to use sudo snapper-gui to see snapshots which is owned by root, but Dolphin (the KDE file explorer, which is called by "Open" botton) complains about that.

Running Dolphin with sudo can cause bugs and expose you to security vulnerabilities. Instead use Dolphin normally and youwill be prompted for elevated privileges when performing file operations that require them.
