After 3.9!? Well, I have no idea of the timescale of your releases, but it’s a common practice to fix current bugs before implementing new features. Although this is a forgotten preferencer or whatevere you’d like to call it, it is a program fault.
I know it’s a small fault, but if you are constantly reminded of this and other small problems you will end up getting annoyed of the program itself. I sincerely hope you will do the changes to include this preference in the next update of MyEclipse.
Since you’re saying it’s a missing preference, this would imply that there is some file somewhere where I can change the property for this “style”? If not, is this a “hardcoded” style? The latter would of course mean more programming to be done.
