Description

There are some things that will be interesting to have in the interactive graph view:

  • Scroll/seek to the first block (entry)
  • Iterate over all the blocks that have no out edges (end/exit nodes)
  • Iterate over all the blocks that have a jump back out edge (loops)
  • Iterate over all nodes that have more than 2 out-edges (jump tables)

We can probably show that in a list in the left side of the screen with "points of interest" for the current graph

Contributor guide

Research direction
Examine the codebase for the interactive graph view, specifically how blocks and edges are stored, and how keyboard navigation is currently handled. Then implement new keybindings for the described navigation features.
