The top line (bar) has indicators for time, battery and angle mode. It also shows "CAS" to know when in CAS or not (in Home). But I find sometimes it would be nice to know if RPN mode is active too. Not applicable to CAS but in Home I would know immediately if my entry needs to be RPN or algegraic. This would also be applicable to the apps (like spreadsheet cell entry).
