JOCELYNPEREZ Hello Joselyn,
Thank you for your question.
You can install two extensions at once although it does not make much sense. You'll get some features basically twice, twice tooltips, and doubled code completions, it will consume twice as much CPU and RAM.
We cannot guarantee all our editor features will work as expected.
Anyways, if there's anything you're missing in our extension, we'll be happy to fix it or implement it.
