OK, you ask for a "special tiddler type". Regarding that particular aspect, I can't answer. But regarding turning new lines into bullet lines I answer this;
If you by "new line" mean double row breaks like you do to make paragraphs in TW normally, then it should be no problem. If you by new line mean to merely break the line which normally in TW doesn't register, then this takes a little more. The former is probably merely to style paragraphs to show a bullet before each <p> The latter can use parts of my newtids <http://newtids.tiddlyspot.com/> macro where such single linebreaks are detected and maniuplated. <:-) -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
