[Invisible dagger]

Ok, sure ill have a go

[Can't Wear Armor Until Improved]

Not without alot of work sadly

[Remove modded armors from smithing]

The easiest route is to do this for yourself.

Load the plugin that has recipes you want hidden in the Creation Kit and add a condition to each recipe that requires the player's level to equal zero. This will effectively hide the recipes as the player can never be at level 0.

 

You probably won't find a mod that does this as it is nigh impossible to keep up with all of the mods that add craftable gear.

 

Side note, some people do prefer to craft their items rather than just adding them via console or some other means.

Not necessarily you could just create anew smithing menu possibly and re assign all old items however that would take alot of work

[Armor Recolor?]

Sadly due to copyright this stuff is very difficult

[Enable Custom Flags and Banner of Nine Hold mod request]
