1. Show maskings in PORTx input and output icons, rather than just the port and value/variable.
It really would be enormously helpful to see this in the flow icons, without having to open the settings for each and every icon to explore whether input or output masks are correct and valid. There's no way of reviewing this crucial aspect from looking at the flow, and on many large programs I've been caught out more times than I care to publicise
2. The Boost compiler often throws out obscure error codes for issues that could be guarded within Flowcode before compile. For example, a formula instead of a variable, or C-styled delimited comment in the wrong place, can result in hours developing the flow only to find that 'somewhere' along the line you've done 'something' that results in an obscure Boost exception error code at build time. Occasionally building to Hex as a check before going too far does help to identify issues earlier though.
Many thanks,
