Modding Questions

So it's been a hot minute since I've last played, and overall I'm too far, 1 maybe 2 dwarves prestige for the first time. context aside point of this post is for modding.

I know the game has an in game mod manager, I haven't used it but I've heard it's doodoo. I know there's one popular one, but my thing is i play on both my pc and steam deck, preferably I'd want one that works on both so I can just have to learn one application. I also have no idea where to download mods so that would be helpful to know.

In terms of mods themselves since Im early I only wanna go for client side stuff, like heat gauges or platform previews. The thing is I read using the in game mod manager tags your game as modded (even with these clientside only mods), but not if your using one of the mod managers.

I probably have other questions but I am blanking, also had to leave and comeback to this post so hopefully this makes sense.
