BETA 115: Various menu items appear to do nothing

What is Send Usage Info supposed to do? Popup a text window with the info? Create a file on disk? The 113 changelog says,

Sends OS, Registration Status, and Version Number
Enable/Disable in menu

What is UI Sync supposed to do?

What is Show Help Texts supposed to do? I assume hover for help text. But it doesn’t appear anywhere I can see.

Also, all of the above menu items aren’t listed in the online User manual.
