Could you provide a brief answer as to why?
Just to make clear - I’m a npp user as you are, so my answer on this is just my assumption nothing official.
In general there isn’t much benefit of having a 64bit over an 32bit version of a program. Memory allocation benefits most
of it but for most “normal” users memory allocation beyond 4GB isn’t important. But making a program work for both
environments isn’t trivial all the time especially when using 3rd party libraries like scintilla which of course must then also support
64-bitness. From npp repository we can see that work is in progress but I can’t say when it is done.
From my point of view I would love to see a warning, in whatever way, if someone edits a file which is assumed to be in system32
but current loaded is different.
Cheers
