I noticed for long time you cannot see well what some players are doing. They moves weird in air and maybe even in afk mode.
It's because you can't see player has menu opened.
Also... if menu (also 2.0) and chat keyboard panel is put bit high in front of you, and if other want speak or sign to you, you cannot see it who is speaking or signing to you. You will not see gesture / signs.
That is simply they didn't see how your panel is put up.
This is why for other side, we need simple semi-transparant panel, with same size as menu panel and chat keyboard panel, they will SEE you opened menu panel or chat keyboard panel and will go around it, to make sure you can see the player.
It's very easy visual fix. In NeosVR for example the panels are visual visible to others. Why should you not do it in VRChat. It helps a lot for others what you're doing there and also make sure you can see him/her.
Really simple solution, we don't need see menu content, only pure area of the panel is enough to see it. Just semi-transparant area of panel. That is good enough and helps better for others. Very important even for deaf people in visual face to face.
In first screenshot my friend is just "behind" menu panel. I can't see him what he is signing.
In second screenshot same reason, it even covers the player, and player don't realize much i can't now see his/her face! That is good for misunderstandings and miss some signing / interaction.
