As always, there may be bugs. Proceed with caution, for now.

Add CheckChatClick action, which can send a message to a player and then react to a click
Add CheckBedrockForm action, which can show Bedrock (via Geyser) players a two-button form and react to responses

A wand without a path assigned will now always have a spell inventory (if using inventory mode)
Custom Recall markers will now use the look direction that was set when creating the marker marker_maintain_direction: true can be used for old behavior
Recall changed to use shift-click to save markers, rather than aiming down
Broomsticks will not let you dismount them until you are near the ground
