I would like to be able to see me on the touchline, have options at the start of what you do like, the aVB stance, stand on the touchline (O'Neil like) or sit down the whole match, have animations of you giving instructions when you use a shout. Could use wages to customise the manager, start of in a simple tracksuit and with wages you can buy suits, touchline stances, etc...
The idea of what your club looks for in youth is a good idea.
Also like the variation in on and off the ball formations.
Isolating players as well, opposing team may have a weak link so I want to exploit it or try and get a player sent off.
Scenarios would be fun to do as well, perhaps from previous seasons. Like FM 12 could have "keep Blackpool in the Prem in 15" for example.
The interview idea for jobs is good, implementing things like what the board want and how you would try and achieve things and what you would do with the squad, signings, how much money you would need, etc. This should be options on new contracts as well for managers, as someone said about adding clauses like "build a new stadium" or "more transfer money". I think this would be really good and could affect staying or leaving a club more.
I would like to be able to start as an Assistant Manager, would make for a good tutorial style start to the game and you could have options like go lower down to manage or stick it out and hope your manager gets sacked and you have a chance to impress. The board could offer a 5/10 game contract where you have to get a set number of points to get the job.
