how about a debugger with this feature ??

how about this nice debug feature

http://www.hut.fi/~amushtaq/debugf1.png

this way, after a break point the programmer can actually see the flow of the code, the if statements etc that were executed ?

or if there is such feature available in some IDE ??

... Interesting... Alternatively you could have it completely strip code that isn't executed so:

Code wrote:

if(something == true)
{
   doStuff();
}
else
{
   doNOTdoStuff(); 
}

Code wrote:

{ doStuff(); }

Code coverage tools sort of do this, but only show the results after the code has run.

I haven't seen code coverage running 'live' in a debugging session yet, but is looks like a good idea to me.

I vote for this one, if anyone from the VS team is looking

It would require a special "heavy debug" target in the compiler because additional code would have to be generated - normal debug info isn't enough to determine which code paths were taken in the procedure ahead of a breakpoint being hit. You need a add a set of flags to the stack-frame and then add instructions that set them when branches are taken (or clear them if they're not). That's more or less what code-coverage tools do.
