Alternatively you could use an external app that has this functionality. Hooking QB64 to external development applications is quite easy :)
The QB64 recommends something called
PSPAD for those on Windows though there are plenty out there and all seem quite easy to hook up the QB64 as all the app needs to run is "qb64.exe -c [your code file here]" to compile your code.
There are pros and cons to this of course. The pros being better OS integration and a more powerful or customisable development interface. The cons include outdated syntax highlighting and most likely a lack of invalid code checking meaning you won't learn of a mistake or typo in your code until you try to compile.
I personally recommend
Geany, but you may find your tastes differ. Just throwing a possible option out there :)
