It is with one caveat. The graphics (for me) have slowed down dramatically when I enter notes with a mouse. Tech Support suggested two fixe: change scroll bar setting and if that didn’t work, do a NVRAM reset. The latter worked briefly, but is back to its old tricks. I need to follow up with them.
I found Notion 6 to be very intuitive and have had success with this product over the years. I cannot say the same for their competitors, they are not as easy to master (for me).
I still highly recommend Notion 6.
