The "Advanced" policy was relaxed a little bit and from that a "Convenient" policy was born.
"Convenient" policy allows freely editing of whole content of files from ./Evolving/ folder, still keeping the advantage of no flashing requirement in between builds.
Mind in a more restrictive "Advanced" policy even printf() strings from ./Evolving/ are ROMed so above property can very useful. That bit of convenience has been traded for increase of RAM usage.
This policy is well suited for SplitCode beginners.
