I think I see your direction. The Acron calculator (from Play Store or iTunes) has a three line menu where the top line is typical of what you'd see on a 42S or 48. The bottom two lines are like the menu buttons that pick a particular menu item list at the top line. Have a look at the app pictures or try out the free version (paid version is quite reasonable!) to see if it sparks some ideas.

So far I replaced indicator and memory registers with a spreadsheet, next I am trying to do dynamic keyboard/menu to implement standard scientific functions to see how and if that idea of keyboard-as-menu even works.
I really like the idea of spreadsheet cells as calculator registers. Referencing another calculator implementation, the go41cxt (tablet version) can show the calculator on the left, printer output on the right and all registers in the middle panel. Very neat for running something like the 41Z module and seeing the contents of registers. If your cells could hold text, matrices, etc. then a column of cells could be like files in the HP-41's extended memory.

A last thought. The pop-up keyboard can easily cover the cell you select and hide what you're typing. Perhaps you could also have a pop-up display, either separate from or attached to the keyboard?
