📋 About This Mod

An engine-level collection of Quality-of-Life improvements in one file with INI settings to enable tweaks.

Fully compatible and recommend for Tale of Two Wastelands and The Frontier.

All features are optional and disabled by default and can be configured by using the Pause->Settings->Tweaks menu (changes are applied when the game is closed and reopened). Launching the game fills out the nvse_stewie_tweaks.ini (available in the optional downloads section). As an alternative to the in-game menu, tweaks can be enabled by modifying the relevant line under the section to be ‘= 1’ instead of ‘= 0’. For hotkey options, change the value under to the desired key .

It is safe to install, configure, update or uninstall mid-playthrough (a new save is not required).

When updating, the mod's INI will be automatically filled with any new settings after launching the game - you do not need to reconfigure settings when updating.
