@dogukanteber If I might beg (yeah, beg!) small changes? But this is fantastically close. As always, thank you for your support!

[dogukanteber]

Of course. My pleasure @chayim.

[chayim]

@dogukanteber Awesome as always. I just merged master back into your branch to make sure that things play nice - and we'll get this in and ready for 4.2.0rc2.

@dogukanteber Sorry, did I miss something? I swear I saw this PR origially including these optoins as items in the function header (i.e separate NX, XX, etc). If not... what do you think about doing that? It would match our other functions!

[dogukanteber]

I have pushed some changes @chayim. Does it match with other functions?

[dvora-h]

@dogukanteber I just pushed a small fix (I hope you don't mind!) so the options will be consistent with options in other functions (like set etc.), now it's ready and we'll include it in the next release, thank you!
