Here's an example of a case where I'd like some formatting in MATH box expressions:
((Drum[V0] | IF(MHR7:0 & C201, RelayWDCfg0:SD, 0)) & IF(C103, -1, RelayPanicCfg0:SD) &
IF(ST4, ~RelayFlashCfg0:SD, -1) & ~RelayTypeTOD0:SD) | (RelayTypeTOD0:SD & TODOutputs0:SD)
Actually doesn't look too bad on screen but hard to follow scrunched up in a little MATH edit box or at runtime.
