This would be helpfu= l because I often select the entire source code,=C2=A0and

In projects with a large number of files, I add header-guards to my header= s,<= /span>

CTRL-M simply= collapses every single collapse block, regardless of context.
=
It wo= uld 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 wh= ich occur
naturally with header guards.

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

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

#pragma endregion // scopes
#pragma endregion // includes
#pragma endregion = = // comments


=

And also sometime like:

#pragma region (disable:= all)

// *All* collapsible regions disabled (comm= ents, includes, function scopes, etc..)

#pragma=C2=A0endregion = // Al= l


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

William Hemsworth
