How do you collect your feedbacks for your SAAS products?

Hey,

Yes, I am building a product that focuses on managing product feedbacks. But this post isn't to pitch hellonext here.

I would like to understand how product makers and product owners manage these feedbacks which we get from many sources. Also, to group them to understand the most important feedbacks? How all these are done so far?

Just trying to understand the product owners here.
