Would recommend you pair usersnap with the free tier of fullstory to dig into user behavior in detail.
Here are solutions to really dig in:
- amplitude for event tracking 
- fullstory to dig into individual users 
- intercom to capture direct feedback 
Coupled to that is very human/design centered process
- regular customer success check ins 
- design synth process to add feedback to our roadmap 
- trello for our product roadmap with weekly senior leadership review
