I know this is a strange question, but are there any external/3rd party mIRC script editors out there? When I code or script I just prefer to use seperate apps for some reason.
Really, any text editor would work if you don't care about automatic formatting (i.e. you insert your own spacing -- don't use TAB to space something out), and if you don't want color-coded script.
I've just found a dll that modifies the build in script editor and adds syntax highlighting ... so far it works great, but ... and that's a big BUT i don't know how safe it is.
