This is not built-in behavior in vispy. You should be able to implement this using picking. See the [picking example](https://github.com/vispy/vispy/blob/main/examples/demo/scene/picking.py), which I think will give you a good start.

I added and deleted a few API tokens today and was surprised to not get any emails about it.

I am also [@aganders3](https://pypi.org/user/aganders3/) there. Edit: sorry I meant the comment above as a suggestion for another opportunity to send emails, not as a complaint!

I think the nature of the problem in the `set_data` call may be ultimately the same. That is, we're basically checking the validity of the symbols twice. As a quick...

`_vispy_mouse_move` will return `None` when it is within 10ms of the last event, I think: https://github.com/vispy/vispy/blob/dad688355f2c21c34cd04e4f639a326fe3c4ac1b/vispy/app/base.py#L199-L200

It works with pre-https://github.com/napari/napari/pull/5701 napari. Adding `"gesture_zoom"` to the cases in [this function](https://github.com/ksofiyuk/napari/blob/0dfb37b474490b4d9829c4fa93cb3d648b4b186d/napari/_vispy/camera.py#L243) (edit: updated the line in that link) will re-enable it but I've been meaning to find time...

It might be okay to enable it that way for now. It's not really part of the API so might not be a breaking change to alter the behavior later...

@psobolewskiPhD are you interested in the rotate gesture for 2D or 3D or both? I think implementing for 3D (we use the vispy AcballCamera) might not be too hard. For...

I don't have a timeline but can start looking into this. I just played with it a bit and we get the appropriate events from vispy, so could potentially do...
