OK, but needs more Edit functionality...

There’s currently no way, on an iPad or iPhone, to edit cells which contain lots of data or lots of text.

All we can currently edit is what’s visible in the box at the bottom of the screen (that’s usually around the middle of the cell).

If you want to edit the start or end of a lengthy cell there’s no way to do that because there’s no way to navigate to anything beyond what’s displayed.

Hard to believe this is a function that’s still missing.
