Question about MQDK.

When you download some of the SDKS, TO START BUILDING THINGS AND WHAT NOT. CAN IT BE USED FOR YOU PERSONALLY? LIKE I WAS READING SOME OF THEM AND IT SAID WOULD HELP WITH THE HAPTICS OF THE CONTROLLER AND HELP WITH HAND TRACKING AND SUCH. SO I WASN’T SURE IF THAT MEANT IT COULD HELP ME TOO ON TOP OF EVERYTHING. BECAUSE I KNOW YOU CAN DOWNLOAD THEM TO YOUR QUEST, SO I WASN’T SURE IF THAT MEANT MY HAND TRACKING WOULD BE BETTER OR IF THAT ONLY MEANT WHEN IT WAS USED AND WHATEVER YOU’RE DEVELOPING STRICTLY.

Yeah, I wasn’t sure if I actually had to be developing an app, to use some of them and make them useful to me personally.. any advice would be greatly appreciated
