username_0: 
<issue_comment>username_1: Hi @username_0 thanks for these changes. Two minor points:

First, the link suppression for `~TiddlyWiki` was intended to avoid the visual complexity when there are multiple references to TiddlyWiki in the same tiddler. I'd be inclined to leave them as is

Secondly, the use of the `rel="noopener noreferrer"` attribute on `<a>` links is intended to solve two problems:

* "noreferrer" to maintain the secrecy of URLs of private TiddlyWiki's (eg on Dropbox)
* "noopener" to avoid this problem: https://mathiasbynens.github.io/rel-noopener/

Both attributes are automatically set for `[[http://google.com]]` style links, but need to be specified manually for `<a>` links
<issue_comment>username_0: I will remove link from CamelCase string 'TiddlyWiki' from that tiddlers.
<issue_comment>username_0: I changed these.
<issue_comment>username_0: I changed these, and I added description about 'rel="noreferrer"' in 'HTML in WikiText'.
<issue_comment>username_1: Hi @username_0 I'm really grateful you're doing this, it's a big job with lots of changes, but makes a big difference. I'm afraid I've noticed one or two more things for which I'll leave line comments.

It must be frustrating for you that this is taking so long to merge. One thought is that it may have been easier to process as separate PRs.

Anyhow, many thanks, and apologies for the delay.
