Since early April, I've discovered 2 new blockchains, Sui and Aptos. Both Sui and Aptos uses the Move language (Sui variant), and both of which uses a subset of the Rust language.
In order to start developing for Move, the best IDE to use is any variant of the IntelliJ IDEA IDE. There is a free version of the IntelliJ IDE, the IntelliJ Community that you can download. After that, you'll need to install Pontem Network's Move plugin.
Once that's settled, you'll be able to create and test Move projects in IntelliJ.

Other than live bindings, you can also use the Observer pattern as a way to update component settings to the Windows registry, an .ini file, or persist it elsewhere.
