1. the toc plugin removes everything except plain text from headers in the toc

# Solutions
There are a few possible solutions to this depending on how it should work:
I would propose implementing the second option because visual markers in headers are useful to convey additional information very fast and this information should be preserved in the toc. Example: Bug or task/project tracker with color conveying status of the bug or task.

It seems you can stuff anything into ordered lists (according to w3.orgs doku), so apart from stylistic reasons and suboptimal display of links in headers (see below) I don't see any problems with markup in the toc.
