Thanks for making this OP! It's a quick way to get people into it viewing it and great to see community fostering.

* I discovered I can translate with ctrl-mouse, but maybe add WASD keys as well?

* I discovered "L" brings up a camera rotation display. The sliders rotates on weird axes (wrong space?), so not too helpful of a UX. Clicking the help magnifier says "Open Filter with CMD+SHIFT+L" but on Safari that opens the sidebar.

* Simple help display for either of those too might help

EDIT: * Tried it on an iPhone 13 Pro... touch controls work great and it is so smooth an good looking. In landscape mode, the header takes up a lot of space. A full-screen button would be great.
