One thing more:
in html snippets, TagComplete and Wrap Selection in Open/Close Tag works just the same, except that:
TagComplete mirrors everything in tags, whilst Wrap Selection in Open/Close Tag mirrors everything in tags but the one matches “s.*”, so that

will not all be mirrored, which also makes more sense.

P.S. Since v9 has snippets enhanced, can we have a Library of snippets, so that users can upload their snippets written?
