It's a little absurd that there are compiler errors that produce line numbers, but we can't see line numbers in the editor. 
Hi,
If you could see them, they would be wrong anyway ( I am guessing ). The errors are generated from the .cpp files that the editor generates, these include a small amount of extra code to turn your Arduino code into conventional c++ with a main() function rather than setup and loop which are both wrapped in the hidden/generated main function()

Actually there are line numbers (in a way)
left in the bottom you can see the current line number
and it corrects for the cpp changes

Well.
I've noticed that number on a few occasions and didn't twig what it's value was indicating...
That's useful.
If there was a folding facility for brackets, that would also be really useful.
The increase in compile speed in 1.0.1 is welcome.
