2)When a wrestler turns you down you have to wait a certain number of cards before you can ask again. What about a feature that gives you notice when you can ask again?

This would be good.  But chances are if a wrestler turns you down once, would you go back to him again, just so that when you hire him, he can walk out on you like sometimes happens in real life?

3)Commentary - like facts about the wrestlers in the match, talk about their last match etc not just so and so puts so and so in a finsher move. Also I get repetition of so and so is bleeding like  a faucet which could be a bit annoying after it is said 5 times in a match.

Kinda like the old tidbits feature from tnm6.2 but have it being said by the announcers during the match instead. This would sort of be like the chant editor I bet as far as programming it goes.

4)Built in Celebrities you can bring in
There should be a database of celebrities that you could bring in like - Jesse Ventura,etc.

Not sure what you are going for with this one.  Because technically if they are interfering, you just type in a name.  If they are wrestling, you would just need a generic wrestler as most "celebrities" are not that well trained in wrestling.  Ventura however, is a former AWA World Tag Team Champion.

5)Bringing people in for 1 card
You should be able to bring in someone for just 1 card and be able to hire them over and over again if its someone you would use sporadically and other times it would be just wasted roster space

Just set your circuit into email mode for this.  That's the easiest way of accomplishing this task.

6)Worker list should only show wrestlers in your circuit
This is just a preference thing but is there really a use to list 1000 or so wrestlers when maybe only 40 or so are actually in your circuit.

I believe this is one of the options that is already available.  It is called "Sorting Options".  You can sorts by the following:

** All Wrestler Alphabetically
** Alphabetical Order, Hired Wrestlers First
** Order By Wrestler Number (pre-TNM 7)

The option you are looking for is #2, the hired wrestlers first option.

7)There should be a list of the top 4 or 5 contenders for each title separately in a different menu so you could see who your top contenders are for specific titles.

Check out the weight class wizard plugin.  This will do EXACTLY what you are asking for.

Win Loss records should be cleaned up after a wrestler leaves, because after a while looking at the overall records gets kind of teidious when you have lost or fired a lot of wrestlers who wont come back (if you play the game fair)

The rankings pages are cleaned up.  I believe what you are talking about is the "wrestler history" pages.  Those are needed for Title Histories to appear properly within the individual circuits you have.

these are just sugestions that i thought would improve the game
