Tablets can use mice and stylii (styluses? styli?) ! It would be super nice if we could indicate affordances with reactive hover effects like we can on desktop. Modern web browsers already support this - I’m not totally familiar with the full web stack under the hood of Obsidian but I imagine most of the work of supporting this has already been taken care of upstream!
Android exposes stylus air-hover through MotionEvent.ACTION_HOVER_ENTER,
ACTION_HOVER_MOVE, and ACTION_HOVER_EXIT, with TOOL_TYPE_STYLUS and
AXIS_DISTANCE.
On Obsidian Android, mouse hover reaches the plugin WebView, but stylus air-hover
does not: the plugin receives pointerType “pen” only when the stylus touches the
screen. This prevents community plugins from showing a pre-contact stylus cursor.
Could Obsidian’s Android WebView host expose native stylus hover to plugins,
for example through a CustomEvent or plugin API carrying x/y, toolType, and
distance? This would enable hover cursors, brush previews, and pen-aware UI
without affecting touch input.
