Post's supplementary / information section - allow more entries

[zbluebugz]

Mentioned in #51

Would like option to hide the Supplementary / Information section via free-text instead of hard-coded lists (Corona virus, Climate, Subscribe)

Currently, this filter component is based on href having certain values - not text-content. List of href values are hard-coded into the script.

Waiting for FB to show me a Supplementary / Information section box again. Will then try and figure out another method of detecting these section boxes and block them by text-content.
