I think it would be cool if there was an option to add first person hand models to your player model.
On one hand I’m up for having some custom viewmodel hands. On the other hand… I don’t need the game showing me how poorly rigged my fingers are. 
Moved to Suggestions (non-Workshop), since this is a feature suggestion and not a suggestion for a mod.
I really hope this feature is implementing soon. Best of luck, I guess…
