UI hide / show on Mouse Button events #30
Description
There's a disturbing behavior of the mouseDown and mouseUp event of the left, mid and right button that, as a side effect, hide or reveal the UI. This behavior doesn't occur while scrolling the wheel (zoom in/out).
This behavior has been noticed both on local installation and on the official website samples, while browsing with no XR device.
Tested on Linux and Windows, Chrome, Firefox and Brave.
Thanks in advance
Regards

Hi,
if you are referring to the new Hathor front-end and UI elements hiding on user interaction, that is intentional.
It was a behaviour also present in the previous version of Hathor, as well as in well-established viewers like SketchFab, to maximize rendered area during user interaction (especially on mobile), temporarily hiding a few UI elements.
It is a specific behaviour of the official front-end, so custom apps can freely adopt (or not) this approach.
Let me know if this was referred to this behavior.
One option would be to provide sort of settings for this in Hathor

Thanks, that's exactly what I was referring to. I found the way to silence this in the public/hathor/uiI.js file... By the way it would be nice to have a toogle to hide/reveal the ui on purpose.. I haven't been into sketchfab for a while, so I don't remember noticing this design. Thanks again for the great job !
