I have some components selected on a lot of separate geometry islands and now I want to "select connected" geometry, so all the separate islands are selected.

But when I LMB double click, only the single island I click on is selected completely.

So I guess there must be a RMB option to "select connected" or "select islands", but it seems there's nothing like that directly available. There's "select all", "select boundary" or "grow selection" etc. but no way to select the connected components.

It seems to only way is to redo the whole selection with the "select 3D connected geometry" active.

Why no simple solution like a RMB > Select connected, or Double click, and all the connected islands are selected ??

Or is there another way to do this ?
