Eclipse took away html editing, which means you can no longer use <s> tags to generate strikethrough text. Fortunately, there's a workaround. You can use this site to generate the same effect. S̶e̶e̶ ̶f̶o̶r̶ ̶y̶o̶u̶r̶s̶e̶l̶f̶!̶
I've been using sites like that since may to stubbornly continue using striked text and subtext (and you can merge the two by copying from one into the other haha)
cause gosh darnit I'm gonna HAVE my tiny text ):<
It's been a year since Eclipse became mandatory, and while some of the functionality and UI issues have been corrected, the majority have not. I wonder if they're understaffed. I'm sure the poor coders are doing the best they can, but management definitely doesn't seem interested in community feedback.
