v0.5.11

Features

• Choose whether a link reaching two questions ahead is drawn as a line or shown as a pair of chips, under Settings > Graphs (9647df5)
• Lines carry arrowheads, so which way a branch runs is readable — including on the long horizontal stretches (36e2650)

Fixes

• Answer labels are no longer hidden behind question bubbles; they sit in the clear band between two rows instead of wherever the line happened to be halfway along (36e2650)
• The back button leaves the editor again instead of rewinding the last chip jump, which read as undoing an edit (9647df5)
