[Feature request] Smart behavior of menu

[Caronte]

When you want to select several options in a menu, you need to enter again and again because the menu is closed after click with LMB

I propose (like in other softwares) the option to use the right mouse button here, but without exit the menu.

Example:
You can chose (RMB) a Theme (inside Scripts window menu) and you can select another one, again and again, until you are happy but without exit the menu every time.

Thanks

P.D: Sorry by my poor English
