Gearing up for the 4th draft

I thought that the 3rd draft of Beacon would be the one that I could sit on and play with for quite a while. It was certainly the one I wanted to really play test a longer campaign with - especially handing out the book for players to use and comment on (read: break).  Well naturally almost as soon as I published it I had a few small changes I wanted to make - the largest being a switch to the silver standard, but also adding in some minor refinements to polearms, initiative and scrolls to make the rules more obvious.  I also thought about adding in level 7 spells which was something I originally wanted to wait on until I saw how the first 6 levels of spells were being used.  I think that the magic system in the SRD kind of falls apart a little once you hit level 7+ and the spells become either too powerful (wish) or not powerful enough (discern location) for the level, or they are basically large versions of lower level spells - something that might work in a spell slot system but not so much in a spell point system where you can bump up the potency or ranges.  So I might like to work on them or maybe high level spells can stay on the back burner a while - I donno.
I also wonder what other things I should try to slide in there.  I do really want to get a longer term draft so I don't want to introduce anything new that might need to be changed, however I also don't want to put out a 5th draft in a month because I absolutely need something for a campaign.  Some suggestions off the top of my head would be;

• add in an explicit speed stat (derived) for movement;
• make a more formal table for combat modifiers;
• write up something about wands and maybe some other magic items;
• add a table for water travel to go with the overland travel table; and
• something just friggin awesome.

I think I'll try to shoot for end of April as a deadline.

*update:  I also noticed that the rules for spellcasting neglect to mention that the target DC is 10 +1 per spell level.  I'll be fixing this as well.
