External Links For Blog questions

[Sapphireslinger]

Just want to make sure before I spend possibly hours changing each link.

1. I'm transferring a bunch of links from my old blogger blog to my new tiddlywiki blog. I want my external web links to open in a new window. I assume this means I need to change:

<a href="https://foo.com/foo">Title</a> (this kind of link opens in the same window taking people away from my blog = bad)

to:

[[Title|https://foo.com/foo]] (this kind of link opens in a different window or tab = good)

Am I correct that I need to take the time to change all those links from one to the other?

2. Regardless of which option I use, do I still need to add rel="noopener noreferrer" to each link, or is that already taken care of somehow behind the scenes in Tiddlywiki?

3. If necessary, is it even possible to add rel="noopener noreferrer" to [[Title|https://foo.com/foo]]?
