Since different camera modes use different multipliers, perhaps the mouse sensitivity solution could be improved by using Wesser's method (Biaxial Mouse Sensitivity). In the post you have it better explained and includes source code. Although it is also included in MixSets, there are many people not so deep into modding that may not even know of its existence, so it would be better to implement it directly in SP, which is the most indispensable and known patch.
