- avoid using const std::unique_ptr& and const std::shared_ptr& - avoid wrapping results in std::optional - prefer std::string_view over const std::string& - update FSUtils::LoadFileToMem to write into std::vector<uint8_t> - use std::span when possible - Avoid unnessecary copies in PluginDataFactory - allocate plugins as HeapMemoryFixedSize which bascially is a std::unique_ptr with fixed size
