This is not really BetterTouchTool related, but I feel it is useful to many - especially if you have a Macbook with a Notch that constantly keeps hiding menu bar status items.
You can show significantly more menu bar status items / icons by reducing the spacing between them. You don't need an app to do that, you can just run these terminal commands:
defaults -currentHost write -globalDomain NSStatusItemSpacing -int 0
defaults -currentHost write -globalDomain NSStatusItemSelectionPadding -int 0
killall ControlCenter
Change the 0 to any spacing value you want to try.
