Example: In this thread a user, using a non-standard Arduino, encountered an issue with memory alignment:
https://www.b4x.com/android/forum/threads/numberformat-problem.79804/#post-505688
The solution that I provided was to create a custom template file for the defines file. With the new feature it can be solved with this line:
#DefineExtra: #define B4R_MEMORY_ALIGNMENT 3
The line as-is will be added to to global defines file and will override the previous value (0).
Which folder? It should be:
C:\Users\<user name>\Documents\Arduino\hardware\espressif\esp32\libraries\WiFi
