a hidden option somewhere that does this more intuitively
Not that I know…
There does exist an Addon called Modifier Tools that has a button to Apply all Modifier on selected Objects, but that won’t work when you have linked copies… The Convert to Mesh has no problem with that situation 🙂
It is one of those things I use so much and the Convert to … are a bit ‘hidden’ in submenus, that I have them in my Quick Favorites and that way, even with only one Object and one Modifier, it is usually the fastest way to get the Modifier Applied, especially when I don’t have the Modifier panel open…
