I mainly code Java with IntelliJ.
- it doesn't AFAIK have an integrated browser or if it does I have never encountered it ❌
- I have not seen it crash a lot and certainly not for the stated reason ❌
- if autocomplete isn't working, that is a sign something about the build process isn't set up right, so other things won't work either ❔
- basic settings being buried deep in the menus is definitely a thing ✅
- if it underlines something, that has always been an error, I think it calls a real Java compiler for this ❌
- freezing at critical moments can occasionally be a thing ✅
