Protontricks is a useful tool for Linux gaming, but it's a bit on the slow and complicated side that Prefixer aims to solve.

If you've never used Protontricks directly - it's a wrapper tool that enables you to run Winetricks commands for games running with Proton / GE-Proton. This is useful for launching external executables, adding needed runtime libraries and so on that sometimes games need to actually run properly (or for major standalone mods).
