Here is a short description of each settting:

* **Show Implicit Converters**: if **on**, the converters which are safe and without parameters are always shown in Bind drawer.
* **Show Incompatible Modifiers**: whether to show incompatible modifiers or not. An incompatible modifier is a modifier that has a `ModifyMode` which is not coherent with the `BindMode`. E.g. a value which is readonly cannot use a writeonly modifier.
* Show Target Replacement: whether to show or not the bind source replacement controls, that is, Group Rebinding.<br>

* **Minimal UI**: enables the Bind fields modern drawers based on UI Toolkit.
* **Optimization**: offers various levels of optimization. The optimization typically consists of a generator building a file with fast access to slow class members. For more info refer to [Performance](https://postica.gitbook.io/binding-system/product/performance) section.
* **Auto Apply Optimization**: when to apply the optimization logic. Three options are available:
  * **Never**: the optimization will never be applied.
  * **On Each Compilation**: will run on each recompilation, thus optimizing in editor as well. May lead to occasional short-lived compile error messages.
  * **On Each Build**: will apply only before building the player. This is the recommended approach.
* **Auto Conversion**: enables an automatic logic which detects field type change and reserializes its value to keep the data consistent. For more info refer to Bind Types Reserialization section.
* **\*Build All AOT Code**: <mark style="color:orange;">not needed anymore</mark>.

* **Build All AOT Code**: how to generate all AOT code required by the BindingSystem. There are several modes:
  * **Skip**: skips the code generation. May be useful when using external generator files. <mark style="color:orange;">No Build Overhead.</mark>
  * **Partial**: generates code only for all types it encounters in scenes to build and resources, along with their dependencies. <mark style="color:orange;">Reduced Build Overhead. Depends on project codebase size, built scenes complexity and number of resources.</mark>
  * **Full**: generates full code. Useful when AssetBundles with bind fields are used. <mark style="color:orange;">Moderate Build Overhead. Depends on project codebase.</mark>
  * **Optimized**: generates only the code which is required for all bind fields in scenes to build and resources, along with their dependencies. <mark style="color:orange;">Minimal Build Overhead. Depends on number of distinct bound fields in built scenes and resources along with their dependencies.</mark>
