how about allowing other players to enter your personal laboratory? In my vision there are several implementation options:

1. by invitation (or whitelist)
2. a checkbox that opens your laboratory to everyone on the team or everyone on the server

it is also not necessary to issue rights to construction/deletion, etc. (usually when a teammate asks to see what he has done, so as not to copy it to the general laboratory)
but at a minimum I would like to see this as an administration tool

How does the shared Force-based lab not meet your needs?

because it’s not always convenient, otherwise I wouldn’t ask about it. for example, even in one team there can be “subgroups” that work on different projects, so as not to mix statistics, they can disperse over different surfaces.
or using an invitation (opening your laboratory) you can quickly show something to another player without having to take it to the general laboratory
besides, as an administrator, I want to see what the players are doing without resorting to the map editor (with subsequent reset of achievements, etc.)
