In short:
Native Settings UI, shown as MODS in the game menu, allows access to CET mods' settings only.
Mods Settings, shown as MOD SETTINGS in the game menu, allows access to Redsctript mods' settings only.

What if you have both types of mods installed?

This QoL mod enables access to both Redscript and CET mods' settings from a single MODS menu.
So you no longer have to guess what's where or navigate through multiple menus to find access to your mod settings.



Key features:

• Adds Redscript Mods to the CET Mods settings menu, allowing access to all mod settings from a single window.
• Allows quick switching between the two settings menus with a single, common button press (C on the keyboard, X on the gamepad).
• Enables Mod Settings to reopen the last visited mod settings page on the next menu open, following the Native Settings UI behavior.
• Allows sorting of the mod list in the Mod Settings to maintain a consistently ordered list.
  

How it works:

Simply install the mod, and it should work out of the box with all the features enabled.

The redscript mods will appear in the Native Settings UI (CET Mods) menu, prefixed with a "•" character to indicate that they are a different type of mod.
Selecting one will open a page in the Native Settings UI with a button that allows you to instantly switch to the mod settings in the Mod Settings menu.
Alternatively, you can press the Go To Red Mods button (the button hint will appear in the action keys hints at the bottom of the menu window).
You can also use the Go To CET Mods button (the same button on the keyboard/gamepad) to switch back to the Native Settings UI menu if needed.

For the best results, please make sure to keep the mod sorting options enabled in both this mod and the Native Settings UI Side Menu Add-on mod (which is the default setting in both mods).

Please note that alphabetical sorting is based on Latin character encoding tables, which may result in incorrect sort orders for non-Latin languages.
However, it will still maintain a consistent order, unlike the default randomly ordered lists.

Limitations:

Switching between Mod Settings and Native UI Settings may not always be perfect due to various differences and caveats in the two mods' functionality.
This specifically applies to changes in sorting settings - after a change, the first altered menu visit may not be accurate.
If you land on a different mod settings page than expected, simply navigate to the correct one.
If you land on the correct mod settings page but the settings are not displayed correctly, just click on another mod and then switch back. Alternatively, you can reopen the menu.

Install or update:

manual (recommended) - drop the extracted "bin" folder into your game folder. Allow to overwrite files if asked.
automatic - use Vortex manager. Please note it may sometimes not work properly due to the Vortex issues. In case of issues please install it manually.

Uninstall:

automatic - use Vortex manager if it was installed by Vortex.
manual - remove the folder:
