All valid points, but a volunteer is needed to implement those suggestions. The team currently maintaining the wiki and ToH does not have the capacity to do significant development work.
Right now, a Dokuwiki datatable plugin is used to realize the ToH and a lot of peculiarities are inherited from it. What would be needed for a truly good user experience would be a dedicated database CRUD application to maintain the ToH data, ideally with some integration into the wiki.
Someone would have to implement that.
