The to-do sheet sits where your thumb can reach it

Tapping a to-do used to open a sheet that nearly filled the screen, with its drag handle pinned up near the top — out of thumb's reach on a phone, and with nowhere left to expand, so dragging up did nothing.

Now the sheet opens at about two-thirds height, so the handle lands around the lower third of the screen. From there:

• Drag up — from the handle or any empty part of the sheet — to expand it to full height.
• Drag down anywhere to shrink it back, or keep going to dismiss it.
• Your buttons and text fields still work normally — a drag only starts on the empty areas, never when you're tapping a control, editing the title, or reordering a checklist.
