You probably won't notice it getting easier, but one day you'll realize that, hey, you just made it up the hill without thinking about it much AND you did it faster than you used to. One thing I've noticed with hills is that a lot of times they don't get noticeably easier, but I DO get noticeably faster at them. I'm maxing out my heart rate still, but I'm getting more power for that same heart rate than I was before.
