Several months have passed since the question was asked (and answered), but, fortunately, everything has changed!
Here is the relevant excerpt from the above blog post:
Marketplace Extension / Gallery
In addition to the extensibility mechanism, we also launched in the product gallery and on the extension website. They allow you to discover and install extensions. To open it in VSCode, just press F1 and select Extensions: Install Extensions .
Alternatively, you can view Marketplace extensions at https://marketplace.visualstudio.com/#VSCode .

I gave the market a quick search and easily found several extensions for spelling and formatting the source code, but I will refuse any specific recommendations, since all the requirements are different.
For those who want to write their own extensions for VSCode, check out the documentation for the VSCode extension , as it has a lot of information needed to start writing its own extensions.
Finally, thanks to Daniel for his comment . This helped me find the information I needed, but in order to save future visitors some time, I thought it was worth sharing my findings.
