Consistent capitalisation of menu items

I tend to capitalise my menus like this:

Title of My Menu

• Item one
  
• Item two
  
• Do something >
  
  

But I notice a lot of apps do this:

Title of My Menu

• Item One
  
• Item Two
  
• Do Something >
  
  

Either way would be fine with me, but having them both annoys me a bit.

Can we maybe "officially" decide on a standard? I'm thinking that could mean

• Accept PRs that fix existing texts to conform to the standard
  
• Don't complain about new texts: we don't want to bother (new) contributors with stuff like this
  
• (Maybe) Do complain about PRs that change existing text so it no longer conforms
  
• (Maybe) Mention it somewhere as being the "preferred" style (but in no way mandatory)
