When I click upload and the serial monitor is open, the IDE closes it for me...
I think it would be a major timesaver if the IDE could open it again after the upload is complete. I've lost count of how many times I've re-opened the serial monitor this week.
Oh yes, I forgot...the "CTRL-Shift-M" shortcut to open the serial monitor is useless because it inserts a newline into the source code.
I agree with fungus, I'd love to see this feature implemented. Having to re-open it after every upload is a bit of a pain.

It would be a major timesaver if you searched before posting, too.

So is wading through posts of people that can't be bothered to do a search first.
This subject has cropped up a lot, but its not that easy to find. Here is a previous post;

If you talk to the Arduino using Hyperterminal and try to do an upload you will get;
processing.app.SerialException: Serial port 'COM25' already in use. Try quiting any programs that may be using it.
But there is no reason why the IDE could not at least re-open the Serial Monitor after it has done an upload - other than the good one that people have bigger fish to fry 
Does anybody know why opening the Serial Monitor or Hyperterminal appears to cause a reset?
When the monitor/hyperterminal opens my sketches are always in setup.
I have just started trying to write a C# program to communicate with the Arduino over the com port and it does not seem to have the same effect.

Totally agree. It's a pain in the a**.
