CTRL-M simply collapses every single collapse block,= regardless of context.
It would be nice to be able to force=C2=A0any region = of code to be strictly non-
collapsible, such as vital comments,=C2=A0= #include'= s, and huge blocks which occur
naturally with header guards.

These are some features which I would like to= see implemented, for the sake
of maintainability and programming efficiency:

#pragma region (disable:comments<= span style=3D"color:rgb(102,102,0)" class=3D"m_6057445883336701859styled-by= -prettify">) =C2=A0 // Prevent both single and m= ulti-line comments from being collapsible.
= #pragma region (= disable:includes) =C2=A0 // Prevent #include's from bei= ng collapsible.
#pragma region (disable:scopes) =C2=A0 = =C2=A0 // Prevent scopes within a function being collapsible.


#pragma en= dregion // scopes
#prag= ma endregion // includes#pragma endregion // comm= ents

<= /b>

And also sometime like:

<= /div>
#pragma region (disable:all)

// *All* collapsible regions di= sabled (comments, includes, function scopes, etc..)

#pragma=C2=A0endregion // All=


<= /font>
Is anything like this c= urrently possible? If not, myself=C2=A0(any probably many= others)=C2=A0would greatly appreciate this feature in the next = update.

Kind Regards,=
William Hemsworth
