Optimized features are always great, especially for those of us who are quite green with FRED. Optimized features ideally always work properly as well, and could ideally be streamlined for performance... of course, that's why they're optimized.
Forgive any redundancy as seen above, but in light of several recent feature requests which could be, despite not being ideal for whatever reason, produced with existing code, could we do something like this: produce pre-compiled code blocks for FRED akin to .h files in C++? Even if just an interm measure for certain code features which ought to have their own dedicated SEXPs or scripts, these portable "header" files could be written and saved in FRED, each containing all the necessary operations for the given feature. Of course, all of those features are already available to FRED, but now they've been packed into a code block which can be saved, easily moved around, and shared with the community much more effectively. Until the replicated feature gets its own dedicated operator (or even needs one), this might be a very useful tool for cutting down on development time.
Last, this was off-topic, but I thought it might be a useful suggestion.
