Kudos!
Feature request: Make it easier to count the number of kills it takes to reach each CL, by including total kills in the "Reached level N" messages. This idea is inspired by Sky's thread about low HP in a starting character. I find recording this info helpful, but I usually forget.
And with this feature there's the possibility of a "pacifist" style Angband competition.

Love the Identify changes
 

The old identify system really used to bug me. It seemed like I could never identify all of the stuff I found. This still looks like it's a possibility, but at least I'll get partial identification on things that have runes I've seen before. Very cool!

Awesome! Now to test it.

- Did you really remove the priestly identify spell or just forget to list it ?

Good point. I just forgot it - it's still in Godly Insights. Also didn't mention Unbarring Ways under traps.

Maybe rings of the mouse are actually valued at 0.
Will check on the treacherous weapon curse.
The pebble one is interesting - I guess it's a bug, but if you had some way of knowing the pebble had gone through the door it wouldn't be.

Ssh! I don't think anyone else had noticed...

Where's my storm of unmagic!! It even made it into poscheng!

Great job on getting 4.1 out the door. Looking forward to where things go from here. (That means you're not allowed to give up yet.)

Still waiting on trees, water, swamp, desert, wilderness, neutrally aligned "p", special levels, quests, .... So many things that make FA great! :D

Congratulations, Nick, and all the Development Team!

Congratulations! I'm really looking forward to playing this.

nice effort guys, way to go~!
