To avoid making a new thread (I’m trying to be e-eco-friendly), I had a couple more decent ideas… One being a message when you level up a skill (can’t believe it took me this long to notice its strange absence). Not sure if it was left out because it could potentially harm immersion for some people, but I’d take a toggle! 
The second thought being an indicator at the end of each message that involves gaining xp. Would look like “You butcher the zombie corpse. (sur 3: 34%)”, where sur = survival, 3 = current survival level, and the percent being current xp amount (COMPLEX SCIENCE!)… Its a little spammy, or would be, but I’d still turn it on if it were offered as a toggle option 
You whack the zombie for 14 damage. (bas 2: 37% mel 3: 12%) for a melee attack with a bashing weapon, etc… or (bash 3-37 melee 3-12)…
Thought I’d throw em out and see
