I don't like having the numbers, (or the change in color) to the code snippets. While the idea is there for tutorial purposes (see line 5), it makes things a lot more difficult to copy and paste the code. While at first glance (in firefox) it seems that you are only copying the selected code (since the numbers don't get highlighted [see first picture attachment]), in practice, (firefox at least) also copies the numbers with the code (see second attachment).
I know that for me, I use code-snippets as a pretty regular part of my programming (hey, wasn't there a snippet for this...?), and it would greatly simplify my projects by just copy and pasting the snippet needed into my project.... If The numbers must absolutely be there, is there an alternative method to copy and pasting the code that won't include the numbers?
