@Martin Capitanio (capnm) Hi Martin. I understand what you're saying, and I have nothing but respect for you by bringing this add-on to light, however please understand I'm not against the add-on bundling per say. What I'm against is sidelining the existing functionality leaving it incomplete by default and patching it on top. Wouldn't it be better to try to improve the current core functionality to behave in the way the add-on works at least?

I wanted to add something to the conversation as well. I'm using v 2.75a and I found out what seems to be the "similar" functionality that you were told about, but as usual it is "almost" hidden for the normal blender user.

It certainly doesn't show up properly in the View menu, nor it works with the pre-assigned keyboard shortcuts. Though it is indeed related to how the currently known View Roll works (pressing NumPad 4 & 6 / CTRL + SHIFT + ScrollWheel for incremental roll).

If you look at the User Preferences > Input > 3D View then search for "View Roll" you'll get all the shortcuts assigned to this "View Roll" you can also see that they all share the same RNA code for python which is VIEW3D_OT_view_roll.rna_type

Anyway, afterwards I took one of the mouse shortcuts and changed the roll type from "Roll Left" to "Roll Angle" then configuring it to work with CTRL+ALT+Middle Press (Shift + NumPad 4 by default), and voila, it works beautifully.

One can also press Spacebar and search for "View Roll"

Despite that there's a catch, Blender native View_OT_roll works "best" while moving the mouse only from left to right, as opposed to your solution which feels more organic and allows the user to mimic the view roll to the mouse / stylus motion, which I feel has a special value especially if one is working with a CINTIQ, and for more specialized work like working with the Grease Pencil for 2D Animation.

Anyway hope this helps clear up to future people what are their choices regarding the "View Roll" functionality. Keep up the great work!

I was having this issue on windows 7 64 bits. however I'm currently testing the following build and I can confirm this issue has been fixed.

Thank you for your hard work Jace!
