I've created a plugin to mimic's Visual Studio Copy/Cut line behavior, inspired by the StackOverflow question on how to get this behavior. The project can be found at https://bitbucket.org/zastrowm/notepad-visualstudiolinecopy
I say new-ish, because I actually created it in .NET a while ago, but I finally ported it to C++, moved it to bitbucket, and provided both Unicode and Ansi assemblies.
If you don't use Visual Studio, what it basically does is:
It's a pretty easy plugin, but very nice to have when coming from Visual Studio.
Have a look to my post, at the address below :
Your plugin has a single feature only, but that feature works perfectly well :-)
So, many thanks for that tiny but very useful plugin !
