This is an intentional re-post of this answer because waffles said so.
The existing boxes for adding "interesting" and "ignored" tags supports wildcards. For example, entering "*friday*" will highlight all of [always-friday-in-iceland]
, [always-hydrogen-on-friday]
, [thank-fsm-its-friday]
&c. as "interesting" (or "ignored").
Can we get similar support on this StackExchange™ GlobalTag MegaBlender™ thing?
