Can anybody please sanity check my Free42/Plus42 skin before I submit it?

In case anybody is interested, I've tweaked my skin some more and the graphic below is where I'm currently at (still haven't submitted it to Thomas yet). As always, any feedback is welcome.

It has been pointed out phones bigger than my iPhone 13 mini could easily hold another row of keys. Alternatively, the screen could be made larger for more lines of display (e.g. for graph plotting etc.). Frankly, I'm of two minds about adding another row - mostly because I'd have to think long and hard about what other 12 functions I'd add. I know Thomas has a row of blank keys across the top on his skin - that would be easy I guess, although I confess to not knowing what purpose they serve.
