I wrote XoR 1 in Notepad++ and found it really helpful, notably the option to set macros for often-typed code snippets like *if aristo, ${simon}, ${lname}, etc.
I’ve started writing XoR 2 in CSIDE and expect I’ll stick with it because of the testing features. Or I might use a combo of Notepad++ for coding and CSIDE for testing…unless and until @CJW finds time to add a macros function like the one I use in Notepad.
